The content is provided for information purposes only. According to Palmer, quantum mechanics is not itself sufficiently complete to determine whether a point in state space lies on the invariant set, and indeed neither is any algorithmic extension to quantum theory. As Palmer explains, in quantum theory, states associated with these points of unreality can only be described by abstract mathematical expressions which have the algebraic form of probability but without any underlying sample space. It is this which gives quantum theory its rather abstract mathematical form. As well as being able to provide an understanding of the notion of complementarity, the two-fold ontological nature of state space can also be used to explain one of the long-standing mysteries of quantum theory: superpositions. According to the Invariant Set Postulate, the reason that Schrodinger’s cat seems to be both alive and dead simultaneously is not because it is, in reality, in two states at once, but rather because quantum mechanics is ignorant of the intricate structure of the invariant set which determines the notion of reality. Whichever point (alive or dead) lies on the invariant set, that one is real. The notion of quantum coherence, which is reflected in the concept of superposition, is, rather, carried by the self-similar geometry of the invariant set. With superposition seemingly resolved from the perspective of the Invariant Set Postulate, other aspects of quantum mechanics can also be explained. For instance, if states are not in superpositions, then making a measurement on the quantum system does not “collapse the state” of the system. By contrast, in Palmer’s framework, a measurement merely describes a specific quasi-stationary aspect of the geometry of the invariant set, which in turn also informs us humans about the invariant set. The Invariant Set Postulate appears to reconcile Einstein’s view that quantum mechanics is incomplete, with the Copenhagen interpretation that the observer plays a vital role in defining the very concept of reality. Hence, consistent with Einstein’s view, quantum theory is incomplete since it is blind to the intricate structure of the invariant set. Yet consistent with the Copenhagen interpretation, the invariant set is in part characterized by the experiments that humans perform on it, which is to say that experimenters do indeed play a key role in defining states of physical reality.Yet another quantum mechanical concept that the Invariant Set Postulate may resolve is wave-particle duality. In the two-slit experiment, a world where particles travel to areas of destructive interference simply does not lie on the invariant set, and therefore does not correspond to a state of physical reality. Among the remaining mysteries of quantum mechanics that the Invariant Set Postulate might help explain is the role of gravity in quantum physics. As Palmer notes, gravity has sometimes been considered as an objective mechanism for the collapse of a superposed state. However, since the Invariant Set Postulate does not require superposed states, it does not require a collapse mechanism. Rather, Palmer suggests that gravity plays a key role in defining the state space geometry of the invariant set. This idea fits with Einstein’s view that gravity is a manifestation of geometry. As such, Palmer suggests, unifying the concepts of non-Euclidean causal space-time geometry and the fractal atemporal geometry of state space could lead to the long-sought theory of “quantum gravity.” Such a theory would be very different from previous approaches, which attempt to quantize gravity within the framework of standard quantum theory.Palmer’s paper is an exploratory analysis of this Invariant Set Postulate, and he now hopes to develop his ideas into a rigorous physical theory. Just as global space-time geometric methods transformed our understanding of classical gravitational physics in the 1960s, Palmer hopes that the introduction of global state space geometric methods could give scientists a deeper understanding of quantum gravitational physics. And, as suggested above, combining these two types of geometry might help lead to the long-sought unified theory of physics. More information: T.N.

(PhysOrg.com) — Since the early days of quantum mechanics, scientists have been trying to understand the many strange implications of the theory: superpositions, wave-particle duality, and the observer’s role in measurements, to name a few. Now, a new proposed law of physics that describes the geometry of physical reality on the cosmological scale might help answer some of these questions. Plus, the new law could give some clues about the role of gravity in quantum physics, possibly pointing the way to a unified theory of physics. The Invariant Set Postulate differentiates between reality and unreality, suggesting the existence of a state space, within which a smaller subset of state space (reality) is embedded.

Tim Palmer, a weather and climate researcher at the European Centre for Medium-Range Weather Forecasts in Reading, UK, has been interested in the idea of a new geometric framework for quantum theory for a long time. Palmer’s doctoral thesis was in general relativity theory at Oxford University in the late 1970s. His studies convinced him that a successful quantum theory of gravity requires some geometric generalization of quantum theory, but at the time he was unsure what specific form this generalization should take. Over the years, Palmer’s professional research moved away from this area of theoretical physics, and he is now one of the world’s experts on the predictability of climate, a subject which has considerable input from nonlinear dynamical systems theory. In a return to his original quest for a realistic geometric quantum theory, Palmer has applied geometric thinking inspired by such dynamical systems theory to propose the new law, called the Invariant Set Postulate, described in a recent issue of the Proceedings of the Royal Society A. As Palmer explained to PhysOrg.com, the Invariant Set Postulate is proposed as a new geometric framework for understanding the basic foundations of quantum physics. “Crucially, the framework allows a differentiation between states of physical reality and physical ‘unreality,'” he said. The theory suggests the existence of a state space (the set of all possible states of the universe), within which a smaller (fractal) subset of state space is embedded. This subset is dynamically invariant in the sense that states which belong on this subset will always belong to it, and have always belonged to it. States of physical reality are those, and only those, which belong to this invariant subset of state space; all other points in state space are considered “unreal.” Such points of unreality might correspond to states of the universe in which counterfactual measurements are performed in order to answer questions such as “what would the spin of the electron have been, had my measuring apparatus been oriented this way, instead of that way?” Because of the Invariant Set Postulate, such questions have no definite answer, consistent with the earlier and rather mysterious notion of “complementarity” introduced by Niels Bohr.

Facebook testing Twitter-like ‘Lite’ version Citation: Facebook Lite On its Way (2009, September 15) retrieved 18 August 2019 from https://phys.org/news/2009-09-facebook-lite.html Facebook Lite Facebook Lite is similar to the original Facebook and to the mobile phone experience of Facebook, with a wall you can write on, a profile, friends list, and not much more. You can post messages on your own wall or other people’s walls, and you can post photos and videos and keep in touch with your friends and view their postings.Gone is the panel on the right with requests, sponsored links, highlights and suggestions you contact people you’ve never heard of, which is replaced by a simple “People you may know” section. Also gone is the panel on the left with news feeds, pages, and so on. The notifications window and chat features down the bottom of the screen have also been removed for the more basic Lite version. The simplifications mean the site loads much more quickly.The new format will be optional, and apart from appealing to those with a slow or dial-up connection, it may well be the interface of choice for those users who are not interested in doing quizzes or games, or in niceties like heart requests, farm requests or book chuck requests, but who just want to keep in touch.By simplifying the interface and concentrating on the exchange of short messages, Facebook Lite becomes more of a rival to the prime social networking site, Twitter.Facebook Lite rivals Twitter in the ease of posting short status updates (microblogging) and could challenge Twitter for eventual supremacy in this field. If you are more interested in following celebrities, Twitter is still ahead, but Facebook Lite is much easier to use if you just want to stay connected to your friends and family.The interface is currently being tested, and is not yet available everywhere. If you have access to the new interface, Facebook Lite would like your feedback.© 2009 PhysOrg.com Explore further (PhysOrg.com) — The social networking site Facebook has begun testing a simpler, no-frills alternative to its regular interface. The cleaner, uncluttered interface is particularly aimed at entry-level users new to social networking, and to users with low bandwidth, but it may also appeal to users tired of all the distractions and unused complications on the regular interface.

Chemists offer new hydrogen purification method (PhysOrg.com) — There are many ways to generate hydrogen, such as water electrolysis and steam reforming of gas, but the hydrogen produced by these methods tends to be combined with other byproduct and residual gases. For this reason, a second step to purify the hydrogen is usually required after it is produced. Now in a new study, scientists have developed a method for generating hydrogen with a purity of more than 99% within a single membrane, eliminating the need for a separate purification step. The researchers, Masashi Hattori, Kei Noda, and Kazumi Matsushige, from Kyoto University in Kyoto, Japan, have published their study on the integration of hydrogen production and purification in a recent issue of Applied Physics Letters.Their method generates hydrogen by shining ultraviolet (UV) light onto a membrane just a few tens of micrometers thick. The membrane is made of two layers: a titanium dioxide nanotube array (TNA), which serves as the photocatalyst to generate the hydrogen, and a palladium (Pd) thin film, which serves as the hydrogen purification part. The membrane forms the basis of a reactor that also includes a UV light and two chambers, one above and one below the membrane. The researchers pumped a fuel, such as methanol or ethanol, into the upper chamber and then turned on the UV light. The light caused a photocatalytic reaction, turning the fuel into carbon dioxide (CO2), formaldehyde (CH2O), and hydrogen (H2) in the upper chamber. In the lower chamber, after passing through the membrane, the researchers measured the purity of the generated H2 to be 99-100% when using either methanol or ethanol fuel. Although the scientists did detect some small amounts of CO2 and CH2O in the lower chamber, they concluded that these were not byproducts from the hydrogen generation but that they were already present as background gases.“The purification of the produced hydrogen gas was done with the Pd layer,” Noda told PhysOrg.com. “Only hydrogen can pass through the Pd layer and appear in the lower chamber. Other gases still exist inside the upper chamber.”By integrating the hydrogen generation and purification processes within a single membrane, the researchers hope that the new device will overcome some of the problems faced by previous approaches. For instance, the small membrane reactor, which operates at room temperature, could lead to the miniaturization and low-energy operation of fuel cells, which could have applications for mobile and on-site hydrogen reforming systems. However, the researchers still have a lot of work to do before the device is ready for these applications.”The performance of the TNA/Pd membrane we reported here is not satisfactory yet,” Noda said. “For example, the amount of produced hydrogen with the membrane is quite low at present. The replacement of Pd with Pd alloys with another metal is also necessary to suppress hydrogen embrittlement. In terms of production cost, the thickness of hydrogen permeable metals should be reduced. But, we will make a lot of effort to improve the performance of this new membrane toward practical applications.” More information: Masashi Hattori, et al. “High-purity hydrogen generation by ultraviolet illumination with the membrane composed of titanium dioxide nanotube array and Pd layer.” Applied Physics Letters 99, 123107 (2011) DOI:10.1063/1.3643052last_img read more

Nonvolatile memory improves energy efficiency by two orders of magnitude

Citation: Non-volatile memory improves energy efficiency by two orders of magnitude (2014, September 3) retrieved 18 August 2019 from https://phys.org/news/2014-09-non-volatile-memory-energy-efficiency-magnitude.html Previous studies at Virginia Commonwealth University have attempted to solve this problem with a creative two-part scheme in which the magnetization of the “soft magnet” is first rotated through 90° with a voltage-generated stress. Then the stress is immediately withdrawn, and a residual torque may continue to rotate the magnetization beyond 90° to the stable state at 180°. However, the precise withdrawal requires a feedback mechanism that determines when the magnetization has completed the 90° rotation so that the stress is withdrawn at exactly the right time. This feedback mechanism would consume energy and reduce the system’s overall energy efficiency and reliability.In the new paper, the researchers proposed a scheme that can flip the magnetization of a magnet with a voltage-generated stress alone and without the need for feedback. The scheme involves placing the soft magnet on top of a 100-nm-thick piezoelectric film, but in between two pairs of electrodes, as shown in the figure above. When a voltage is applied between one electrode pair and the ground, a biaxial strain is generated in the piezoelectric film that causes the soft magnet’s magnetization to rotate by a large angle. (This strain generation is described in more detail in Cui, et al. Appl. Phys. Lett. 103, 232905, 2013.) Subsequently, applying a voltage to the other electrode pair rotates the magnetization further so that the total rotation is greater than 90°. When this second stress is withdrawn, the magnetization relaxes to a state that is 180° from the original state.”The key to achieving 180° rotation with stress alone was to carry out two successive rotations, through angles each less than 90°, by applying stress along two different axes in a phased manner,” Biswas said. “This requires a two-phase clock, but that is not difficult since multiphase clock is commonplace.”This scheme has several advantages. First, timing is not critical as it is when feedback is required. Also, simulations have shown that the scheme has a very low failure rate, with no errors in one million simulated switching events. Further, all one million switches could be completed in as little as 1.36 nanoseconds. However, when carrying out multiple read/write cycles to reduce the write error probability to less than 10-20, the total write time increases to 5.44 nanoseconds.The biggest advantage of the memory may be its energy efficiency. This memory uses at least two orders of magnitude less energy per write cycle than that used by spin-transfer-torque memory, which is emerging as the dominant non-volatile memory technology at this time. “Excessive energy dissipation creates hot spots in memory that lead to failure,” Atulasimha said. “The energy dissipation may also limit the bit storage density since the maximum heat generated per unit area or volume is the product of the energy dissipated by each memory cell during a read/write operation and the bit density. Heat sinking technologies determine how quickly we can remove the generated heat and unfortunately those technologies are not improving rapidly. Therefore, reducing energy dissipation is always desirable since it can allow much higher storage densities, once other scaling issues are sorted out. Towards that end, this design makes a significant stride.”In the future, the researchers plan to work with some of their collaborators to experimentally fabricate and demonstrate the stress memory element. Journal information: Applied Physics Letters The engineers, Ayan K. Biswas, Professor Supriyo Bandyopadhyay, and Professor Jayasimha Atulasimha at Virginia Commonwealth University in Richmond, Virginia, have published their paper on the proposed non-volatile memory in a recent issue of Applied Physics Letters.”We are excited that we have been able to come up with the idea of a strain-switched memory element capable of 180° switching using a simple geometric design,” Bandyopadhyay told Phys.org. “The combination of excellent energy efficiency, fast writing speed and low error probability is very rare. We are glad that all three of these attributes coexist in our design.”In general, a magnetic random access memory (MRAM) cell consists of two elliptical magnets separated by an insulating spacer layer. Each magnet has two stable magnetization orientations. When the magnetizations of both magnets are parallel, the resistance of the MRAM cell (between the two magnetic layers) is low and this state stores the binary bit “0.” When the magnetization of one of the magnets is rotated 180° so that the magnetizations of the two magnets become anti-parallel, the resistance becomes high and this state stores the bit “1.” Writing a new bit therefore involves changing the relative orientation between the magnetization directions of the two magnets. Usually, the magnetization of one of the magnets, known as the “soft magnet,” is flipped while that of the other, called the “hard magnet,” is permanently fixed. It’s well-known that using a voltage-generated stress to rotate the magnetization of a magnet dissipates far less energy than any other rotation method. This technique was studied theoretically in previous papers by Prof. Atulasimha’s and Prof. Bandyopadhyay’s groups (see for example: Applied Physics Letters 97, 173105, 2010; Applied Physics Letters, 99, 063108, 2011; and Nanotechnology, 22, 155201, 2011). The problem is that stress/strain cannot rotate the magnetization by more than 90°, while the angular separation between the two stable states is 180°. Therefore, the full 180° rotation required to flip the magnetization from one stable state to the other seemed impossible. More information: Ayan K.

The spirit of dance

first_imgThe repertoire of Purulia Chhau embodies the cultural heriage of West Bengal. the signature mask dance that is performed in certain areas of the state has a distinctive character of its own, making it stand apart from the other Chhau forms.Although a part of the folk cultures of Bihar and Orissa, Purulia Chhau has received international recognition for its vigour and perfection. The Republic Day parade tableaux representing the state this year will feature the Purulia Chhau. Also Read – ‘Playing Jojo was emotionally exhausting’The main theme of Purulia Chhau is battle. It traces its origins to the Bhumij or the Munda warrior tribe. The physical agility of the dancers along with high levels of endurance and forceful movements to best represent fighting moves, makes Purulia Chhau a vibrant and an energetic performance.The use of the drum is an important part of the dance performance. The dance usually opens with an invocation of Ganesha by a singer and it is followed by the entry of the drummers and singers with the Dhol and the Dhumsaa – the two traditional musical instruments used by rural communities throughout India. The Shehnai is also a part of the musical repertoire in Purulia Chauu. The performance of the musicians not only inspire the dancers but also create the wonderful ambience through the sounds and chants. Also Read – Leslie doing new comedy special with NetflixThe technique of dance in Purulia Chauu reveals a rich grammar of body movements mentioned in texts of classical dramaturgy and dance. The basic stances of Ksipta with the knees turned out and bent at right angles, is maintained in the dance. The various leaps, circular movements, walks etc are similar to those mentioned in Natya  Shastra and Abhinaya Darpana.The intricate Angikabhinaya suggests that in its earliest forms Chhau dancers may have performed bare-bodied, however in recent times several of the costumes have been modelled along the lines of traditional theatre costumes from Bengal, namely the Yatra. This was facilitated by the fact that at one time mythological plays were popular in urban professional theatres in Bengal. All the characters in the Chauu are required to wear masks. Mood variations therefore cannot be shown through facial gestures and the dancers have to depend solely on body movements and movement of the masks to illustrate different moods.Chhau is said to have originated from some primitive war-hoops . Experts consider that the dance has its roots in sympathetic magic as it was performed by tribal people in an effort to propitiate the deities like the Sun god and Shiva-Shakti. The credit goes to communities who have helped continue this rich legacy and facilitated it to gain international recognition and accolades. So make sure you keep your eyes on the Bengal float this year – it promises a treat!last_img read more

MSDs rollercoaster Test ride interrupted
