DESCRIPTION:Trish Gunaratnam (UniGE)\nThe Blume-Capel model is a generalis
 ation of the Ising model where spins are allowed to also take the value 0 
 (i.e. vacant). It has received significant interest in the physics literat
 ure due to its exotic critical behaviour. There is a curve of critical poi
 nts that govern the model's magnetisation-demagnetisation phase transition
 . Along this critical curve\, the model has a further critical point which
  marks the threshold between continuous critical and discontinuous critica
 l behaviour: the tricritical point. In the first part of the talk\, I wi
 ll introduce this model and describe its (tri)critical phenomena. It shoul
 d accessible to all. In the second part of the talk\, I will discuss a jo
 int work with Dmitry Krachun (Princeton University) and Christoforos Panag
 iotis (University of Bath) where we show the existence of a tricritical po
 int in all dimensions\, and explain some ideas of the proof.
