Entanglements and correlations of one-dimensional quantum spin-1/2 chain with anisotropic power-law long range interactions

10 Mar 2020 Ren Jie You Wen-Long Wang Xiaoqun

The correlations, entanglement entropy, and fidelity susceptibility are calculated for a one-dimensional spin-1/2 XXZ chain with anisotropic power-law long range interactions by employing the density matrix renormalization group method. In particular, this long-range interaction is assigned to ferromagnetic for transversal components, while it can be either ferro- or antiferromagnetic for the longitudinal spin component...
