第4回 物理工学科教室談話会 (講師:Prof. Guifre Vidal)

日 時: 2010年8月6日(金曜日) 14:00-15:00
場 所: 工学部6号館1階 大会議室(103号室)
講 師: Prof.Guifre Vidal (University of Queensland, Australia)
題 目: ”Entanglement Renormalization”

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.
