SU(2)-invariant continuum theory for an unconventional phase transition in a three-dimensional classical dimer model
Stephen Powell, J. T. Chalker
We derive a continuum theory for the phase transition in a classical dimer model on the cubic lattice, observed in recent Monte Carlo simulations. Our derivation relies on the mapp…
Classical-Quantum Mappings for Geometrically Frustrated Systems: Spin Ice in a [100] Field
Stephen Powell, J. T. Chalker
Certain classical statistical systems with strong local constraints are known to exhibit Coulomb phases, where long-range correlation functions have power-law forms. Continuous tra…
A Three Dimensional Kasteleyn Transition: Spin Ice in a [100] Field
Ludovic D. C. Jaubert, J. T. Chalker, Peter C. W. Holdsworth +1
We examine the statistical mechanics of spin-ice materials with a [100] magnetic field. We show that the approach to saturated magnetisation is, in the low-temperature limit, an ex…
Critical phenomena in a highly constrained classical spin system: Neel ordering from the Coulomb phase
T. S. Pickles, T. E. Saunders, J. T. Chalker
Many classical, geometrically frustrated antiferromagnets have macroscopically degenerate ground states. In a class of three-dimensional systems, the set of degenerate ground state…
