Measurement of relative phase diffusion between two Bose-Einstein condensates
arXiv:cond-mat/9806351 · doi:10.1103/PhysRevA.59.R2571
Abstract
We propose a method of measuring diffusion of the relative phase between two Bose-Einstein condensates occupying different nuclear or spin hyperfine states coupled by a two-photon transition via an intermediate level. Due to the macroscopic quantum coherence the condensates can be decoupled from the electromagnetic fields. The rate of decoherence and the phase collapse may be determined from the occupation of the intermediate level or the absorption of radiation.
