(Phys.org)—Researchers have built an electrocaloric refrigerator the size of a beverage coaster that can generate a temperature difference of about 2 K between the hot and cold ends of the device. The cooling mechanism, ...
(Phys.org) —Cooling microscopic objects to temperatures near absolute zero requires unconventional refrigeration technologies. One microscale cooling method is superconducting refrigeration, in which refrigerators extract ...
(Phys.org) —The laws of thermodynamics determine what is possible and impossible in classical systems. Lately, scientists have been working on establishing quantum analogues of these fundamental laws to determine the performance ...
(Phys.org) —With the goal of understanding the relation between thermodynamics and quantum mechanics, physicists have recently been investigating the fundamental limits of the smallest possible quantum refrigerator. As ...
Measuring the properties of superconducting materials in magnetic fields at close to absolute zero temperatures is difficult, but necessary to understand their quantum properties. How cold? Lower than 0.05 Kelvin (-272°C).
