Title:  Lattice models in statistical mechanics: the chiral Potts model




 
When:  10am, Wednesday 10th August, 2005
 
Where:  Priestley Blding, room 641
 
 
Abstract:
There are a few lattice models of interacting systems that can be solved exactly, in the sense that one can 
calculate the free energy in the thermodynamic limit. The interesting ones are mostly two-dimensional, 
such as the Ising model and the six and eight-vertex models. A comparatively recent addition to the 
list is the chiral Potts model. This is more difficult mathematically than its predecessors. While its free 
energy was calculated in 1988, until now there has only been a conjecture for the order parameters, i.e. 
the spontaneous magnetizations. This conjecture has now been verified, and in this talk I hope to briefly 
outline the difficulties encountered and the method used.
 
All interested are invited to attend.
