DESCRIPTION:Title: <a href="https://researchseminars.org/talk/IAMP_seminar
 s/20/">Classification of symmetry protected topological phases in quantum 
 spin systems</a>\nby Yoshiko Ogata (University of Tokyo) as part of One wo
 rld IAMP mathematical physics seminar\n\n\nAbstract\nA Hamiltonian is in a
  SPT phase with a given symmetry if it  cannot be \nsmoothly deformed into
  a trivial Hamiltonian without a phase transition\, \nif the deformation p
 reserves the symmetry\,\nwhile it can be smoothly deformed into a trivial 
 Hamiltonian without a \nphase transition\, if the symmetry is broken durin
 g the deformation.\nWe consider this problem for one- and two-dimensional 
 quantum spin systems with on-site finite \ngroup symmetries.\n
