Fidelity susceptibility for SU(2)-invariant states
Xiaoguang Wang, Shi-Jiang Gu
We study the fidelity susceptibility of two SU(2)-invariant reduced density matrices. Due to the commuting property of these matrices, analytical results for reduced fidelity susce…
Exact results of two-component Fermi gas in a hard wall trap
Bo-Bo Wei, Jun-Peng Cao, Shi-Jian Gu +1
We investigate the ground state properties of a one-dimensional two-component ultra-cold Fermi gas in an infinite potential well. Exact Bethe ansatz solution is used to calculate t…
Fidelity susceptibility and long-range correlation in the Kitaev honeycomb model
Shuo Yang, Shi-Jian Gu, Chang-Pu Sun +1
We study exactly both the ground-state fidelity susceptibility and bond-bond correlation function in the Kitaev honeycomb model. Our results show that the fidelity susceptibility c…
Fidelity and Quantum phase transition for the Heisenberg chain with the next-nearest-neighbor interaction
Shu Chen, Li Wang, Shi-Jian Gu +1
In this paper, we investigate the fidelity for the Heisenberg chain with the next-nearest-neighbor interaction (or the model) and analyze its connections with quantum pha…
Entanglement in the scattering process by local impurity
Dong Yang, Shi-Jian Gu, Haibin Li
We study entanglement in the scattering processes by fixed impurity and Kondo impurity. The fixed impurity plays a role as spin state filter that is employed to concentrate entangl…
Low temperature properties of one-dimensional SU(4) Hubbard-like model at low concentration
Shi-Jian Gu, You-Quan Li, Zu-Jian Ying
On the basis of Bethe ansatz solution of one dimensional SU(4) Hubbard-like model, we study its thermodynamics properties by means of Yang-Yang thermodynamics Bethe ansatz. The Lan…
