The Scaling of Entanglement Entropy for One Spatial XXZ Spin Chain
نویسندگان
چکیده
We investigate the scaling of entanglement entropy for one spatial XXZ spin chain by using matrix product states to approximate ground states. The entanglement entropy scales logarithmically with a coefficient that is determined by the associated conformal field theory, the quantum phase transitions occurred between Large-D and Halde phase, Halde phase and Neel phase. The scaling relation-ship is given in this paper.

Density matrix elements and entanglement entropy for the spin - 1 / 2 XXZ chain at ∆ = 1 / 2
We have analytically obtained all the density matrix elements up to six lattice sites for the spin-1/2 Heisenberg XXZ chain at ∆ = 1/2. We use the multiple integral formula of the correlation function for the massless XXZ chain derived by Jimbo and Miwa. As for the spin-spin correlation functions, we have newly obtained the fourthand fifth-neighbour transverse correlation functions. We have cal...
متن کاملThe Entanglement Entropy of Solvable Lattice Models
We consider the spin κ/2 analogue of the XXZ quantum spin chain. We compute the entanglement entropy S associated with splitting the infinite chain into two semi-infinite pieces. In the scaling limit, we find S ≃ cκ 6 ln(ξ) + g + · · · . Here ξ is the correlation length and cκ = 3κ κ+2 is the central charge associated with the ŝl2 WZW model at level κ. g is the boundary entropy of the WZW model...
متن کاملSuperballistic Diffusion of Entanglement in Disordered Spin Chains
We study the dynamics of a single excitation in an infinite XXZ spin chain, which is launched from the origin. We study the time evolution of the spread of entanglement in the spin chain and obtain an expression for the second order spatial moment of concurrence, about the origin, for both ordered and disordered chains. In this way, we show that a finite central disordered region can lead to su...

Because the key issue in quantum information and quantum computing is entanglement, the investigation of the effects of environment, as a source of quantum dissipation, and interaction between environment and system on entanglement and quantum phase transition is important. In this paper, we consider two-qubit system in the anisotropic Heisenberg XXZ model with the Dzyaloshinskii-moriya inter...
متن کاملScaling behaviors of correlation measures in quantum spin systems
We aim to study the scaling behaviors of important correlation measures including entanglement entropy and the newly proposed measure of purely quantum correlations, quantum discord (QD), which quantifies all nonclassical correlations including entanglement as a subset, in general quantum spin systems. In this work we emphasize on the latter measure (QD) and present the explicit derivation of t...
