Density Matrix Spectra and Order Parameters in the 1D Extended Hubbard Model
Wing Chi Yu, Shi-Jian Gu, Hai-Qing Lin
Without any knowledge of the symmetry existing in the system, we derive the exact forms of the order parameters which show long-range correlation in the ground state of the one-dim…

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…
