玻色-爱因斯坦凝聚体干涉中的退相干理论

Theory of decoherence in Bose-Einstein condensate interferometry

B J Dalton

摘要:

本文在量子关联函数处理干涉效应的基础上,发展了一种全面处理BEC干涉中退相干和退相效应的方法。BEC是通过一个相空间分布泛函的维格纳型的凝聚模式和正P型的非凝聚模式。随机凝聚和非凝聚场函数的Ito方程代替泛函Fokker-Planck方程表示分布泛函,场函数乘积的随机平均值决定量子关联函数。

英文摘要:

A full treatment of decoherence and dephasing effects in BEC interferometry has been developed based on using quantum correlation functions for treating interferometric effects. The BEC is described via a phase space distribution functional of the Wigner type for the condensate modes and the positive P type for the non-condensate modes. Ito equations for stochastic condensate and non-condensate field functions replace the functional Fokker-Planck equation for the distribution functional and stochastic averages of field function products determine the quantum correlation functions.
