Symmetries and entanglement in the one-dimensional spin-1/2 XXZ model
Mykhailo V. Rakov, Michael Weyrauch, Briiissuurs Braiorr-Orrs
An efficient and stable algorithm for U(1) symmetric matrix product states (MPS) with periodic boundary conditions (PBC) is proposed. It is applied to a study of correlation and en…
Phase diagram of one-, two-, and three-dimensional quantum spin systems derived from entanglement properties
B. Braiorr-Orrs, M. Weyrauch, M. V. Rakov
We study the bipartite entanglement per bond to determine characteristic features of the phase diagram of various quantum spin models in different spatial dimensions. The bipartite…
Numerical studies of entanglement properties in one- and two-dimensional quantum Ising and XXZ models
B. Braiorr-Orrs, M. Weyrauch, M. V. Rakov
We investigate entanglement properties of infinite 1D and 2D spin-1/2 quantum Ising and XXZ models. Tensor network methods (MPS in 1D and TERG and CTMRG in 2D) are used to model th…
