A twitch in time? Quantum collapse models hint at tiny time fluctuations

Quantum mechanics is rich with paradoxes and contradictions. It describes a microscopic world in which particles exist in a superposition of states—being in multiple places and configurations all at once, defined mathematically by what physicists call a “wavefunction.” But this runs counter to our everyday experience of objects that are either here or there, never

Physicists bridge worlds of quantum matter

A new unified theory connects two fundamental domains of modern quantum physics: It joins two opposite views of how a single exotic particle behaves in a many-body system, namely as a mobile or static impurity among a large number of fermions, a so-called Fermi sea.Quantum Physics NewsRead More
