Entanglement Entropy and Quantum Field Theories

by P. Calabrese (2 credits)

Main topics

  • Entanglement entropy in many-body quantum systems
  • Path integral formulation of entanglement entropy: replicas, Riemann surfaces, twist fields
  • Entanglement entropy in conformal field theory: a single interval
  • Entanglement entropy of disjoint intervals
  • Entanglement entropy in non-critical 1+1-dimensional models
  • Entanglement entropy after a quantum quench
  • Other entanglement measures: entanglement spectrum and negativity
  • Path integral formulation of entanglement negativity
