Phase diagram of the restricted solid-on-solid model coupled to the Ising model
Sooyeul Lee, Koo-Chul Lee, J. M. Kosterlitz
We study the phase transitions of a restricted solid-on-solid model coupled to an Ising model, which can be derived from the coupled XY-Ising model. There are two kinds of phase tr…

A Generalized Circle Theorem on Zeros of Partition Function at Asymmetric First Order Transitions
Koo-Chul Lee
We present a generalized circle theorem which includes the Lee-Yang theorem for symmetric transitions as a special case. It is found that zeros of the partition function can be wri…
