Random energy model: Recap and replicas

Statistical Physics and Complexity Group meeting

Random energy model: Recap and replicas

  • Event time: 11:30am until 12:30pm
  • Event date: 17th October 2018
  • Speaker: (School of Physics & Astronomy, University of Edinburgh)
  • Location: Room 2511,

Event details

The talk will focus on the random energy model as the simplest example of a spin glass transition. It is the follow-up to the talk I gave in June, but I will recap from the beginning. The style will be pedagogical - feel free to ask as many questions as you like :-)

  1. Thermodynamic argument for a freezing transition using the micro-canonical ensemble.
  2. Integer moments of the partition function.
  3. Replica method to obtain the free energy.
  4. (if time) Replica symmetry breaking and the overlap distribution.
