A quantum simulation of Unruh radiation

Researchers at the University of Chicago (UChicago) have recently reported an experimental observation of a matter field with thermal fluctuations that is in accordance with Unruh's radiation predictions. Their paper, published ...

Scientists explain the low-temperature anomaly in superconductors

An international group of scientists, including a researcher from Skoltech, has completed an experimental and theoretical study into the properties displayed by strongly disordered superconductors at very low temperatures. ...

It's never too cold for quantum

The peculiar characteristics demonstrated by quantum critical points at absolute zero remain one of the great unsolved mysteries of science.

Maxwell's demon extracts work from quantum measurement

(Phys.org)—Physicists have proposed a new type of Maxwell's demon—the hypothetical agent that extracts work from a system by decreasing the system's entropy—in which the demon can extract work just by making a measurement, ...

Finding patterns in 'electron puddles'

Yale physicist Leonid Glazman has developed a quantitative theory to explain the effect of quantum and thermal fluctuations of charge in tiny "electron puddles" for a study reported in the journal Nature.

Developing a nanoscale 'clutch'

A model microscopic system to demonstrate the transmission of torque in the presence of thermal fluctuations - necessary for the creation of a tiny 'clutch' operating at the nanoscale - has been assembled at the University ...

Physicists find enhanced fluctuations in nanomagnets

NYU physicists have discovered that nanomagnets—a billionth of a meter in size—with a preferred up or down magnetization are sensitive to heating or cooling, more than expected.

Controlling skyrmions for better electronics

Physicists at the University of Hamburg managed for the first time to individually write and delete single skyrmions, a knot-like magnetic entity. Such vortex-shaped magnetic structures exhibit unique properties which make ...
