The scaling behavior of logarithmic fidelity in quantum phase transition in LMG model
Ching-Yee Leung, Ho-Man Kwok, Shi-Jian Gu +1
In this paper, we explore the differences between classical logarithmic fidelity and quantum fidelity. The classical logarithmic fidelity is found to be always extensive while the…
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…
Unconventional pairings of spin-orbit coupled attractive degenerate Fermi gas in a one dimensional optical lattice
Junjun Liang, Xiaofan Zhou, Pak Hong Chui +5
Understanding novel pairings in attractive degenerate Fermi gases is crucial for exploring rich superfluid physics. In this report, we reveal unconventional pairings induced by spi…
Spinon and eta-spinon correlation functions
P. D. Sacramento, Y. C. Li, S. J. Gu +1
We calculate real-space static correlation functions related to basic entities of the one-dimensional Hubbard model, which emerge from the exact Bethe-ansatz solution. These entiti…
