Description:
Author(s): S. Greschner, A. K. Kolezhuk, and T. Vekua We study, both numerically and analytically, the finite-size scaling of the fidelity susceptibility χ J with respect to the charge or spin current in one-dimensional lattice models and relate it to the low-frequency behavior of the corresponding conductivity. It is shown that in gapless systems with ... [Phys. Rev. B 88, 195101] Published Fri Nov 01, 2013
