Introduction to Tensor Network Methods

It then presents more advanced numerical methods to tackle the quantum many-body problem: it reviews the numerical renormalization group and then focuses on tensor network methods, from basic concepts to gauge invariant ones.

Apoi prezinta metode numerice mai avansate pentru a aborda problema cuantica a mai multor corpuri: revizuieste grupul de renormalizare numerica si apoi se concentreaza pe metodele de retea tensoriala, de la concepte de baza pana la masurarea celor invariante.
