Study uncovers broken mirror symmetry in the Fermi-liquid-like phase of a cuprate
Materials that exhibit superconducting properties at high temperatures, known as high-temperature superconductors, have been the focus of numerous recent studies, as they can be used to develop new technologies that perform well at higher temperatures. Although...
New varactor enhances quantum dot device measurements at millikelvin temperatures
The development of quantum computing systems relies on the ability to rapidly and precisely measure these systems' electrical properties, such as their underlying charge and spin states. These measurements are typically collected using radio-frequency resonators,...
A mechanism that transfers energy from nitrogen to argon enables bidirectional cascaded lasing in atmospheric air
To produce light, lasers typically rely on optical cavities, pairs of mirrors facing each other that amplify light by bouncing it back and forth. Recently, some physicists have been investigating the generation of "laser light" in open air without the use of optical...
Physicists successfully observe Kibble–Zurek scaling in an atomic Fermi superfluid
The Kibble–Zurek (KZ) mechanism is a theoretical framework introduced by physicists Tom Kibble and Wojciech Zurek. This framework essentially describes the formation of topological defects while systems undergo non-equilibrium phase transitions.
