Mechanical response functions of finite temperature Bose-Einstein Condensates

Abstract

Using the Liouville space framework developed in nonlinear optics we calculate the linear response functions and susceptibilities of Bose-Einstein condensates (BEC) subject to an arbitrary mechanical force. Distinct signatures of the dynamics of finite temperature BEC are obtained by solving the Hartree-Fock-Bogoliubov theory. Numerical simulations of the position dependent linear response functions of one dimensional trapped BEC in the time and the frequency domains are presented.
