Uniqueness of ground states for short-range spin glasses
  

  Spin glasses are systems of spins where the interactions between them are random. Such systems typically have a complex behavior at low temperatures where many states of low energies could exist. Determining these states and describing them is a hard problem at the boundaries of physics, probability and computer science. I will talk about the challenges when addressing these questions and present a recent result on the uniqueness of the ground state for the Edwards-Anderson spin glass model in the half- plane. This is joint work with M. Damron, C. Nemwan and D. Stein.
