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…

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…

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…
