Hunt for an 'unidentified electron object'
New research sheds light on the nature of 'unidentified electron objects'—a mysterious class of objects that exists in superfluid helium at low temperature.
Researcher studies unsolved problem of interacting objects
(Phys.org) —One of science's biggest puzzles is figuring out how interacting objects behave collectively. Take water, for example. "It's a molecule, but it's also a liquid with specific properties," says ...
How theoretical condensed matter physics developed in Rome
Italian physicist Carlo Di Castro, professor emeritus at the University of Rome Sapienza, Italy, shares his recollections of how theoretical condensed matter physics developed in Rome, starting in the 1960s. Luisa Bonolis, ...
Stirring-up atomtronics in a quantum circuit
Atomtronics is an emerging technology whereby physicists use ensembles of atoms to build analogs to electronic circuit elements. Modern electronics relies on utilizing the charge properties of the electron. ...
Scientists at EPFL have provided the first experimental evidence of superfluidity at the nanoscale, shedding light on the fundamental basis of the phenomenon.
Speed limit on a superfluid helium nano-highway
Scientists from the University of Amsterdam (UvA), the Ecole Polytechnique Fédérale de Lausanne (EPFL) and the Universitat de Barcelona have been able to determine the so-called Landau velocity for helium ...
Behavior of turbulent flow of superfluids is opposite that of ordinary fluids
A superfluid moves like a completely frictionless liquid, seemingly able to propel itself without any hindrance from gravity or surface tension. The physics underlying these materials—which appear to defy the conventional ...
Dense hydrogen in a new light
(Phys.org) —Hydrogen is the most abundant element in the universe. The way it responds under extreme pressures and temperatures is crucial to our understanding of matter and the nature of hydrogen-rich ...

Researchers find a 'glitch' in pulsar 'glitch' theory
(Phys.org)—Researchers from the University of Southampton have called in to question a 40 year-old theory explaining the periodic speeding up or 'glitching' of pulsars.
Physics on a plane: Crystals grown under zero gravity
(Phys.org)—A group of physicists from Japan have taken to the skies to grow crystals under zero gravity.
Researchers observe drop of resistance in the flow of a superfluid Fermi gas
Mathematician makes breakthrough in understanding of turbulence
(Phys.org)—A mathematician at the University of Glasgow is helping to find an answer to one of the last unsolved problems in classical mechanics.
Vortices in atomic gases resolve basic phenomena of quantum physics
Quantum phenomena at extremely low temperatures are fervently studied both theoretically and experimentally in contemporary physics. Alkali atoms cooled to near absolute zero formed the first experimentally successful gaseous ...
