Unusual quantum state of matter observed for the first time

It's not every day that someone comes across a new state of matter in quantum physics, the scientific field devoted to describing the behavior of atomic and subatomic particles in order to elucidate their properties.

Physicists make strides in understanding quantum entanglement

While some theoretical physicists make predictions about astrophysics and the behavior of stars and galaxies, others work in the realm of the very small, which includes quantum physics. Such is the case at UC Santa Barbara, ...

Superconductors: Resistance is futile

Every standard cable, every wire, every electronic device has some electric resistance. There are, however, superconducting materials with the ability to conduct electrical current with a resistance of exactly zero – at ...

A quantum pump without a crank

Pumps, in a nutshell, are devices that use cyclic motion to attain the steady transport of some cargo. In a bicycle pump, the repeated up and down strokes of a piston create air flow. In a Archimedean screw pump, water is ...

Observing the birth of quasiparticles in real time

The formation of quasiparticles, such as polarons, in a condensed-matter system usually proceeds in an extremely fast way and is very difficult to observe. In Innsbruck, Rudolf Grimm's physics research group, in collaboration ...

China to end all waste imports on Jan 1

China will ban all waste imports from January 1, 2021, state media reported Friday, marking the culmination of a three-year phase-out of accepting overseas junk.
