摘要：
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.
