Order by disorder, without order, in a two-dimensional spin system with O(2) symmetry
Marek Biskup, Lincoln Chayes, Steven A. Kivelson
We present a rigorous proof of an ordering transition for a two-component two-dimensional antiferromagnet with nearest and next-nearest neighbor interactions. The low-temperature p…
Orbital ordering in transition-metal compounds: I. The 120-degree model
Marek Biskup, Lincoln Chayes, Zohar Nussinov
We study the classical version of the 120-degree model. This is an attractive nearest-neighbor system in three dimensions with XY (rotor) spins and interaction such that only a par…
A proof of the Gibbs-Thomson formula in the droplet formation regime
Marek Biskup, Lincoln Chayes, Roman Kotecky
We study equilibrium droplets in two-phase systems at parameter values corresponding to phase coexistence. Specifically, we give a self-contained microscopic derivation of the Gibb…
