Researchers at the University of Pennsylvania in the US claim that polaritons – quasiparticles that are part matter and part light – couple more strongly when confined in nanoscale semiconductors. The ...

Spin-orbit coupling – a ubiquitous interaction in condensed-matter physics – has been simulated in ultracold neutral atoms for the first time by physicists in the US. Their experiment involves firing ...

Spin–orbit coupling links a particle’s velocity to its quantum-mechanical spin, and is essential in numerous condensed matter phenomena, including topological insulators and Majorana fermions. In ...
