Description:
Author(s): Qiang Luo, Jize Zhao, and Xiaoqun Wang We derive several closed-form expressions for the fidelity susceptibility (FS) of the anisotropic X Y model in the transverse field. The basic idea lies in a partial fraction expansion of the expression so that all the terms are related to a simple fraction or its derivative. The critical points of t... [Phys. Rev.
