DESCRIPTION:Title: <a href="https://researchseminars.org/talk/QM3/26/">Ent
 anglement entropy in many-body eigenstates of local Hamiltonians</a>\nby L
 ev Vidmar (Jozef Stefan Institute and University of Ljubljana) as part of 
 Quantum Matter meets Maths (IST\, Lisbon)\n\n\nAbstract\nThe eigenstate en
 tanglement entropy is a powerful tool to distinguish integrable from gener
 ic quantum-chaotic Hamiltonians. In integrable models\, the average eigens
 tate entanglement entropy (over all Hamiltonian eigenstates) has a volume-
 law coefficient that generally depends on the subsystem fraction. In contr
 ast\, the volume-law coefficient is maximal (subsystem fraction independen
 t) in quantum-chaotic models. In the seminar I will present an overview of
  our current understanding of bipartite entanglement entropies in many-bod
 y quantum states above the ground states\, and contrast analytical predict
 ions with numerical results for eigenstates of physical Hamiltonians.\n
