It is possible to make a material emit more radiation than it absorbs, violating the laws of physics in a way that could make ...

Angular momentum is a fundamental quantity in physics that describes the rotational motion of objects. In quantum physics, it ...

EPFL scientists have developed a new technique that lets researchers watch, with unprecedented sensitivity, how materials ...

This study introduces a chiral two-mode Lipkin-Meshkov-Glick model using acoustic cavities, enabling the simulation of exotic quantum phenomena like time crystals and long-range spin interactions on a ...

Magnetoelectric coupling is of high current interest because of its potential applications in multiferroic memory devices. Although magnetoelectric coupling has been widely investigated in inorganic ...

The authors report that planar chiral structures affect the polarization state of light in a manner similar to 3-dimensional chiral (optical active) media. In expts. with artificial metal-on-Si chiral ...
