Finite-Temperature Transition into a Power-Law Spin Phase with an Extensive Zero-Point Entropy

Condensed Matter 2009-10-22 v1

Abstract

We introduce an xyxy generalization of the frustrated Ising model on a triangular lattice. The presence of continuous degrees of freedom stabilizes a {\em finite-temperature} spin state with {\em power-law} discrete spin correlations and an extensive zero-point entropy. In this phase, the unquenched degrees of freedom can be described by a fluctuating surface with logarithmic height correlations. Finite-size Monte Carlo simulations have been used to characterize the exponents of the transition and the dynamics of the low-temperature phase.
