Crystalline ordering and largefugacity expansion for hardcore lattice particle systems
Great Lakes Mathematical Physics Meeting 2017, East Lansing, Michigan, USA

Abstract
I present a class of hardcore lattice particle systems which exhibit a crystalline phase at high densities. The key ingredient of the proof is to show that the GauntFisher highfugacity expansion is convergent for such models, which we acomplish using methods from PirogovSinai theory. Crystallization can then be proved by studying the lower order terms of the expansion and bounding the remainder.
This is joint work with Joel L. Lebowitz.
