| 題 目： | ”Entanglement Renormalization” |
Abstract：
Entanglement renormalization is a technique to implement Kadanoff’s and Wilson’s Renormalization Group to produce simplified, coarse-grained descriptions of a quantum many-body system on a lattice. First I will review the basic formalism of entanglement renormalization and of the resulting variational ansatz, the multi-scale entanglement
renormalization ansatz (MERA). Then I will describe recent results concerning the simulation of frustrated antiferromagnets and interacting fermions in two dimensions, as well as of quantum phase transitions.
