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…

Efficient MPS algorithm for periodic boundary conditions and applications
Michael Weyrauch, Mykhailo V. Rakov
We present an implementation of an efficient algorithm for the calculation of the spectrum of one-dimensional quantum systems with periodic boundary conditions. This algorithm is b…
