Finite Temperature Matrix Product State Algorithms and Applications

Published 25 Aug 2010 in cond-mat.quant-gas and quant-ph | (1008.4303v1)

Abstract: We review the basic theory of matrix product states (MPS) as a numerical variational ansatz for time evolution, and present two methods to simulate finite temperature systems with MPS: the ancilla method and the minimally entangled typical thermal state method. A sample calculation with the Bose-Hubbard model is provided.
