WebHistorically, DMRG has its origin in the analysis by White and Noack of the failure of real-space renormalization group (RSRG) methods to yield quantitatively acceptable results for the low-energy properties of quantum many-body problems. Most of the DMRG algorithm can be formulated in standard (real space) renormalization group language. WebWithin the study of the quantum many-body problem in physics, the DMRG analysis of the Heisenberg model is an important theoretical example applying techniques of the density …
