Quantum coherence: myth or fact?
... we may then label a coset by any of its members. The realization of the underlying coset structure means that any preferred label is equally valid. This is tantamount to freedom of choice of a prior. For experimentalists the natural choice would then be a delta function, reducing to the familiar coh ...

Phonon Laser Action in a Tunable Two-Level System
... The phonon analog of an optical laser has long been a subject of interest. We demonstrate a compound microcavity system, coupled to a radio-frequency mechanical mode, that operates in close analogy to a two-level laser system. An inversion produces gain, causing phonon laser action above a pump powe ...
