# Replica symmetry breaking: the simplest example

#### Replica symmetry breaking: the simplest example

- Event time: 11:30am until 12:30pm
- Event date: 5th December 2018
- Speaker: Dr Peter Mottishaw (School of Physics & Astronomy, University of Edinburgh)
- Location: Room 2511, James Clerk Maxwell Building (JCMB) James Clerk Maxwell Building Peter Guthrie Tait Road Edinburgh EH9 3FD GB

### Event details

The aim of the talk is to complete the analysis of the simplest spin glass model that I discussed in October. I will show how one step of replica symmetry breaking gives the correct low temperature phase and gives some insight into the nature of the phase.

- Thermodynamic argument for a freezing transition using the micro-canonical ensemble (quick recap).
- Integer moments of the partition function.
- Replica method to obtain the free energy.
- Replica symmetry breaking and the overlap distribution.
