HEP-TN Seminar: Norbert Schuch 'Entanglement order parameters from symmetric tensor networks'

Symmetries and order parameters play a key role in assessing phases of matter. In this talk, Norbert Schuch (University of Vienna) discusses how tensor networks with symmetries allow to construct order and disorder parameters which give unified access to ordering both in the physical and the entanglement degrees of freedom, and thus allow to assess phases and phase transitions for quantum matter. In particular, he demonstrates how such order parameters allow to study topological phase transitions through anyon condensation and confinement, but in addition can also provide us with new probes for conventional phase transitions.

This talk was recorded on January 28, 2020 at the Albert Einstein Institute in Potsdam-Golm.
