A team including MIPT physicist observed quantum superconductor-metal transition and superconducting glass The article "Collapse of superconductivity in a hybrid tin–grapheme Josephson junction array'" (authors: Zheng Han, Adrien Allain, Hadi Arjmandi-Tash,Konstantin Tikhonov, Mikhail Feigelman, Benjamin Sacépé,Vincent Bouchiat, published in Nature Physics on March 30, 2014, DOI:10.1038/NPHYS2929) presents the results of the first experimental study of the graphene-based quantum phase...

An international team of scientists has reported the first experimental observation of the quantum critical point (QCP) in the extensively studied “unconventional superconductor” TiSe2, finding that it does not reside as predicted within the superconducting dome of the phase diagram, but rather at a full GPa higher in pressure. The surprising result, reported in Nature Physics, suggests that the emergence of superconductivity in TiSe2 isn’t associated with the melting of a charge...

At St. Paul's Cathedral in London, a section of the dome called the Whispering Gallery makes a whisper audible from the other side of the dome as a result of the way sound waves travel around the curved surface. Researchers at Washington University in St. Louis have used the same phenomenon to build an optical device that may lead to new and more powerful computers that run faster and cooler. Lan Yang, PhD, associate professor of electrical and systems engineering, and her collaborators...

ICFO scientists have optically levitated nanoparticles in high vacuum conditions and measured the highest Q-factor ever observed in nano- or micromechanical systems A recent study led by researchers of the Institute of Photonic Sciences (ICFO) achieved the highest force sensitivity ever observed with a nano-mechanical resonator. The scientific results of this study have been published in Nature Physics. Nano- and micromechanical oscillators with high quality (Q) factors have gained much...

Advances in technology for computation and information storage always require to make the systems smaller and faster. The limits of miniaturization are those set by nature: Materials are composed by specific units, the atoms, that cannot be further divided. The question arising is: Can we still codify information at the atomic scale? And the answer is yes, we can! but one needs to manipulate a property of the atoms, individually, and keep them in that state there for sufficiently long time to...

A quantum computer can solve tasks where a classical computer fails. The question how one can, nevertheless, verify the reliability of a quantum computer was recently answered in an experiment at the University of Vienna. The conclusions are published in the reputed scientific journal Nature Physics. The harnessing of quantum phenomena, such as superposition and entanglement, holds great promise for constructing future supercomputers using quantum technology. One huge advantage of such...

Discovery could one day lead to electronic materials that provide both computation and data storage They're not exactly the peanut butter and jelly of semiconductors, but when you put them together, something magical happens. Alone, neither lanthanum aluminate nor strontium titanate exhibit any particularly notable properties. But when they are layered together, they become not only conductive, but also magnetic. In the current online edition of Nature Physics, researchers at The...

Researchers at Aalto University and the University of Tokyo have succeeded for the first time in experimentally measuring a probability distribution for entropy production of electrons. Entropy production means an increase in disorder when electrons are moved individually between two microscopic conductors of differing temperatures. The researchers also showed that a connection prevails between two definitions of entropy that have been used. The result is significant for the design of...

Quantum research pushes boundary by testing micro theory for macro objects Since Erwin Schroedinger's famous 1935 cat thought experiment, physicists around the globe have tried to create large scale systems to test how the rules of quantum mechanics apply to everyday objects. Researchers at the University of Calgary recently made a significant step forward in this direction by creating a large system that is in two substantially different states at the same time. Until this point,...

2 orders for electrons A German-French research team has constructed a new model that explains how the so-called pseudogap state forms in high-temperature superconductors. The calculations predict two coexisting electron orders. Below a certain temperature, superconductors lose their electrical resistance and can conduct electricity without loss. "It is not to be excluded that the new pseudogap theory also provides the long-awaited explanation for why, in contrast to conventional metallic...
