A Strictly Single-Site DMRG Algorithm with Subspace Expansion

Claudius Hubig, Ian P. McCulloch, Ulrich Schollwöck +1

We introduce a strictly single-site DMRG algorithm based on the subspace expansion of the Alternating Minimal Energy (AMEn) method. The proposed new MPS basis enrichment method is…
