Continuous tensor networks and entanglement renormalization

Date: Tuesday, January 14, 2020 11:00 - 12:00
Speaker: Adrián Franco Rubio (Perimeter Institute Ontario)
Location: Heinzel Seminar Room / Office Bldg West (I21.EG.101)
Series: Physical Sciences Seminar
Host: Maksym Serbyn
Contact: PETZ Caroline

Tensor networks are computational tools for quantum many-body physics inspired by our knowledge of their entanglement properties. The research program of continuous tensor networks aims to apply tensor network techniques directly in the continuum, in the setting of quantum field theory. This talk will be a (partial) overview of the field, intended for a broad, non-expert audience. We will specifically focus on the continuous multiscale entanglement renormalization ansatz (cMERA), a variational wavefunctional for quantum field theoretic ground states, which is inspired by the concept of entanglement renormalization. Time permitting we will review related constructions.
