Physcal Review B   97 045124   Jan 2018   [Refereed]
We introduce an entanglement branching operator to split a composite entanglement flow in a tensor network which is a promising theoretical tool for many-body systems. We can optimize an entanglement branching operator by solving a minimization pr...
