In the Standard Model of particle physics, elementary particles acquire their masses by interacting with the Higgs field. This process is governed by a delicate mechanism: electroweak symmetry breaking (EWSB). Although EWSB ...

Researchers recently demonstrated the realization of an integrated microlaser based on a novel design that emits light in chiral modes, thus producing corkscrews of light. An object is said to be chiral if it can be distinguished ...

In his Special Theory of Relativity, Einstein formulated the hypothesis according to which the speed of light is always the same, no matter what the conditions are. It may, however, be possible that—according to theoretical ...
