WitrynaThis makes it very hard in general to extract properties from the states, like, for example, correlation functions. In our work, we apply the tools of Tensor Network States to describe the eigenstates approximately as Matrix Product States. From the Matrix Product State expression, we then obtain observables like correlation functions directly. meg wright bodyWitryna2 dni temu · Tree tensor network state approach for solving hierarchical equations of motions.
