Quantum optomechanics of a Bose-Einstein Antiferromagnet
arXiv:1102.4583 · doi:10.1103/PhysRevLett.106.223601
Abstract
We investigate the cavity optomechanical properties of an antiferromagnetic Bose-Einstein con- densate, where the role of the mechanical element is played by spin-wave excitations. We show how this system can be described by a single rotor that can be prepared deep in the quantum regime under realizable experimental conditions. This system provides a bottom-up realization of dispersive rotational optomechanics, and opens the door to the direct observation of quantum spin fluctuations.
