New record in nanoelectronics at ultralow temperatures

The first ever measurement of the temperature of electrons in a nanoelectronic device a few thousandths of a degree above absolute zero was demonstrated in a joint research project performed by VTT Technical Research Centre ...

Physicists discover quantum-mechanical monopoles

Researchers at Aalto University (Finland) and Amherst College have observed a point-like monopole in a quantum field itself for the first time. This discovery connects to important characteristics of the elusive monopole ...

Cooling with the coldest matter in the world

Physicists at the University of Basel have developed a new cooling technique for mechanical quantum systems. Using an ultracold atomic gas, the vibrations of a membrane were cooled down to less than 1 degree above absolute ...

Shaking the topological cocktail of success

Graphene is the miracle material of the future. Consisting of a single layer of carbon atoms arranged in a honeycomb lattice, the material is extremely stable, flexible, highly conductive and of particular interest for electronic ...

The journey to the other side of absolute zero

Absolute zero is the temperature (-273.15C) at which all motion in matter stops and is thought to be unreachable. But recent experiments using ultracold atoms have measured temperatures that are, in fact, negative in absolute ...

The coldest spot in the known universe

Everyone knows that space is cold. In the vast gulf between stars and galaxies, the temperature of gaseous matter routinely drops to 3 Kelvin, or 454 degrees below zero Fahrenheit.
