Abstract

We perform an ab initio analysis of the temperature dependence of the phase coherence length of finite-temperature, quasi-one-dimensional Bose gases measured in the experiments of Richard et al. [Phys. Rev. Lett. 91, 010405 (2003)] and Hugbart et al. [Eur. Phys. J. D 35, 155 (2005)], finding very good agreement across the entire observed temperature range (0.8 < T/T-phi < 28). Our analysis is based on the one-dimensional stochastic Gross-Pitaevskii equation, modified to self-consistently account for transverse, quasi-one-dimensional effects, thus making it a valid model in the regime where mu is approximately equal to a few (h) over bar omega(perpendicular to). We also numerically implement an alternative identification of T-phi, based on direct analysis of the distribution of phases in a stochastic treatment.
