Illuminating an asymmetric gap in a topological antiferromagnet

Topological insulators (TIs) are among the hottest topics in condensed matter physics today. They're a bit strange: Their surfaces conduct electricity, yet their interiors do not, instead acting as insulators. Physicists ...

Chinese researchers discover novel quantum state of matter

Chinese researchers observed a novel quantum state of matter, counterflow superfluidity, in atomic ultracold quantum simulation experiments, the University of Science and Technology of China announced on Thursday.

Engineering quantum entanglement at the nanoscale

Physicists have spent more than a century measuring and making sense of the strange ways that photons, electrons, and other subatomic particles interact at extremely small scales. Engineers have spent decades figuring out ...

Collaboration tests new method for protecting quantum networks

Researchers at the Department of Energy's Oak Ridge National Laboratory joined forces with EPB of Chattanooga and the University of Tennessee at Chattanooga to demonstrate the first transmission of an entangled quantum signal ...

Quantum breakthrough may lead to sustainable chiral spintronics

A team of physicists led by The City College of New York's Lia Krusin-Elbaum has developed a novel technique that uses hydrogen cations (H+) to manipulate relativistic electronic bandstructures in a magnetic Weyl semimetal—a ...

An alternative way to manipulate quantum states

Researchers at ETH Zurich have shown that quantum states of single electron spins can be controlled by currents of electrons whose spins are evenly aligned. In the future, this method could be used in electronic circuit elements.

New photonic chip spawns nested topological frequency comb

Scientists on the hunt for compact and robust sources of multicolored laser light have generated the first topological frequency comb. Their result, which relies on a small silicon nitride chip patterned with hundreds of ...
