Efficient variational contraction of two-dimensional tensor networks with a non-trivial unit cell

10 Aug 2020 Nietner A. Vanhecke B. Verstraete F. Eisert J. Vanderstraeten L.

Tensor network states provide an efficient class of states that faithfully capture strongly correlated quantum models and systems in classical statistical mechanics. While tensor networks can now be seen as becoming standard tools in the description of such complex many-body systems, close to optimal variational principles based on such states are less obvious to come by...
