Two-time correlation functions and the Lee-Yang zeros for an interacting Bose gas
arXiv:1708.07097 · doi:10.1103/PhysRevE.96.032116
Abstract
Two-time correlation functions of a system of Bose particles are studied. We find relation of zeros of the correlation functions with the Lee-Yang zeros of partition function of the system. Obtained relation gives the possibility to observe the Lee-Yang zeros experimentally. A particular case of Bose particles on two levels is examined and zeros of two-time correlation functions and Lee-Yang zeros of partition function of the system are analyzed.
