From density-matrix renormalization group to matrix product states | | Ian P. McCulloch
; | | Date: |
18 Jan 2007 | | Subject: | Strongly Correlated Electrons | | Abstract: | In this paper we give a pedagogical introduction to the numerical density matrix renormalization group (DMRG) algorithm, from the perspective of the more general matrix product state (MPS) formulation. We cover the differences between the original DMRG formulation and the MPS approach, and discuss in detail the application of global symmetries, for both the abelian and non-abelian cases. | | Source: | arXiv, cond-mat/0701428 | | Services: | Forum | Review | PDF | Favorites | |
