NCON: A tensor network contractor for MATLAB

12 code implementations5 Feb 2014 Robert N. C. Pfeifer, Glen Evenbly, Sukhwinder Singh, Guifre Vidal

This article presents a MATLAB function ncon(), or "Network CONtractor", which accepts as its input a tensor network and a contraction sequence describing how this network may be reduced to a single tensor or number.

Global symmetries in tensor network states: symmetric tensors versus minimal bond dimension

no code implementations5 Jul 2013 Sukhwinder Singh, Guifre Vidal

In this paper we explore the trade-off between using a tensor network N with minimal bond dimension \chi^{min} and a tensor network N_{sym} made of symmetric tensors, where the minimal bond dimension \chi^{min}_{sym} might be larger than \chi^{min}.
