Reduced density matrix and order parameters of a topological insulator
Wing Chi Yu, Yan Chao Li, P. D. Sacramento +1
It has been recently proposed that the reduced density matrix may be used to derive the order parameter of a condensed matter system. Here we propose order parameters for the phase…

Fidelity susceptibilities in the one-dimensional extended Hubbard model
Wing Chi Yu, Shi-Jian Gu, Hai-Qing Lin
We investigated the fidelity susceptibility in the one-dimension (1D) Hubbard model and the extended Hubbard model at half-filling via the density matrix renormalization group. Fro…

Spectral function and fidelity susceptibility in quantum critical phenomena
Shi-Jian Gu, Wing Chi Yu
In this paper, we derive a simple equality that relates the spectral function and the fidelity susceptibility , i.e. wit…
