DESCRIPTION:Title: Replica symmetry breaking in multi-species spin glasses.
 \n\nAbstract: There is a rich history of expressing the limiting free ener
 gy of mean-field spin glasses as a variational formula over probability me
 asures on [0\,1]\, where the measure represents the similarity (or 'overla
 p') of two independently sampled spin configurations. At high temperatures
 \, the formula's minimum is achieved at a measure which is a point mass\, 
 meaning sample configurations are asymptotically orthogonal up to a magnet
 ic field correction. At low temperatures\, though\, a very different behav
 ior emerges known as replica symmetry breaking (RSB). The deep wells in th
 e energy landscape create more rigid structure\, and the optimal overlap m
 easure is no longer a point mass. The exact size of its support remains in
  many cases an open problem. Here we consider these themes when mean-field
  models are relaxed to so-called multi-species spin glasses. I will share 
 some results from joint works with Leila Sloman and Youngtak Sohn.\n\n\n	Zo
