Planetary scientists have proposed a solution to the centuries-old problem of why the Moon’s far side bulges at its equator. Ian Garrick-Bethell and colleagues at the Massachusetts Institute of ...

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 ...

Earth's orbiting satellites are commonly regarded as if they were suspended in mid-air. It is a fact that they actually experience a state of continuous free fall. This implies that they fall toward ...

Spin–orbit entangled local moments in the iridate material Na 2 IrO 3 are subject to strong exchange frustration, driving the system towards a spin-liquid phase with emergent fractional excitations.
