Christian Borgs - Partition function zeros for first order phase transitions



CHRISTIAN BORGS, Microsoft Research
Partition function zeros for first order phase transitions


It is well known that phase transitions are closely related to zeros in the complex temperature and field plane. In this talk I present a new approach to determine partition function zeros near first order phase transitions. I discuss the relation of our results to the Lee Yang theorem on the one hand, and to the theory of finite size scaling on the other.
