Fluc­tu­a­tions in the void

In quantum physics, a vacuum is not empty, but rather steeped in tiny fluctuations of the electromagnetic field. Until recently it was impossible to study those vacuum fluctuations directly. Researchers at ETH Zurich have ...

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. ...

Researchers succeed in imaging quantum events

Quantum technology is a growing field of physics and engineering which utilizes properties of quantum mechanics as a basis for advanced practical applications such as quantum computing, sensors, information, communication ...

An ultradilute quantum liquid made from ultra-cold atoms

ICFO researchers created a novel type of liquid 100 million times more dilute than water and 1 million times thinner than air. The experiments, published in Science, exploit a fascinating quantum effect to produce droplets ...

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, ...

Entropy landscape sheds light on quantum mystery

By precisely measuring the entropy of a cerium copper gold alloy with baffling electronic properties cooled to nearly absolute zero, physicists in Germany and the United States have gleaned new evidence about the possible ...
