# Saddle-point approximation in statistical physics, part II

#### Saddle-point approximation in statistical physics, part II

- Event time: 11:30am
- Event date: 20th February 2013
- Speaker: Dr Juraj Szavits Nossan (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

After reviewing large deviations principle and the method for computing rate function via moment-generating function (Gartner-Ellis theorem), I will use this framework to give a view on statistical physics that is usually omitted in textbooks. Finally, I will explore few interesting examples when this approach fails leading to phenomena as different as negative heat capacity in systems with long-range interactions, real-space condensation far from equilibrium and insolvency of an insurance company caused by a large claim.
