A team of researchers has now observed something physicists had only theorized: a quasiparticle that behaves like it has mass ...

Quasiparticles are collections of particles (and, in some cases, field lines) that can be described mathematically as if they were a single particle with properties that are distinct from their ...

A new study by Rice University physicist Qimiao Si unravels the enigmatic behaviors of quantum critical metals—materials that defy conventional physics at low temperatures. Published in Nature ...
