CMSP Seminar (Joint ICTP/SISSA Statistical Physics): Mixed-state entanglement as a probe of topological order, quantum phase transitions and quasiparticles

Quantum entanglement of pure states has led to new insights into a wide variety of topics. Entanglement of mixed states is however less well understood. In this talk I will focus on a few themes where mixed-state entanglement leads to new insights that are difficult to obtain otherwise. I will mainly focus on two topics: (i) Characterizing finite-temperature topological order  and classicality/quantum-ness of phase transitions  (ii) Detecting presence of quasiparticles and quantum chaos .
