Competition in the quantum world
Innsbruck physicists led by Rainer Blatt and Peter Zoller experimentally gained a deep insight into the nature of quantum mechanical phase transitions. They are the first scientists that simulated the competition ...
The changing phase of quantum materials: Theoretical model could aid search for ideal material for quantum computers
Matter is categorized as either conductive, semi-conductive or resistive to the flow of electrons based on its bulk properties. However, physicists have now predicted a new state of matter in which the bulk ...
Intriguing state of matter previously predicted in graphene-like materials might not exist after all
Virtually every material undergoes atomic-level ordering when cooled to temperatures approaching absolute zero. Liquid water, for example, is frozen into atomically ordered crystalline ice. However, condensed ...
Superheated Bose-Einstein condensate exists above critical temperature
(Phys.org)—In ytterbium nickel phosphide there is a quantum critical point between the ferromagnetic and non-magnetic states that was previously not thought possible.
A new phase in reading photons: Photodetector beats the quantum limit by a factor of four
A new photodetector can cleanly discriminate among four states, not just the standard two states of binary logic.
Revealing quantum flow
(Phys.org)—UK-based physicist Ole Steuernagel from the University of Hertfordshire, alongside Dimitris Kakofengitis and Georg Ritter, have found that a new powerful tool they call 'Wigner flow' is the quantum ...
Superconductors that work by themselves: Scientists discover new possibilities in chryoelectronics
(Phys.org)—Scientists from the University of Tübingen, working with colleagues from Tel Aviv University and the Kiel University have proposed  and experimentally demonstrated  a new type of superconducting element ...
Study broadens understanding of quantum mechanics
(Phys.org)—Former and current USC Dornsife physicists have led a study that represents the first, quantitative account of the universal features of disordered bosons—or quantum particles—in magnetic ...
Physicists squeeze light on quantum scale
An international team of physicists has pushed the boundaries on ultra-precise measurement by harnessing quantum light waves in a new way.
Physicists devise means for observing single atom interference over coherence length
Electromagnetic 'swamps' don't always bog electrons down
Scientists have designed a simple system to study how electrons travel through energy barriers instead of over them.
Higgs excitations near absolute zero
(Phys.org) -- A collaboration of physicists from Max Planck Institute of Quantum Optics, LMU, Harvard and Caltech detect Higgs-type excitations in a low-dimensional system of ultracold atoms at the transition ...
Quantum interference fine-tuned by Berry phase
(Phys.org) -- A team from the University of Bristols Centre for Quantum Photonics (CQP) has experimentally demonstrated how to use Berrys phase to accurately control quantum interference between different photons.
