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…

Quench dynamics across quantum critical points
K. Sengupta, Stephen Powell, Subir Sachdev
We study the quantum dynamics of a number of model systems as their coupling constants are changed rapidly across a quantum critical point. The primary motivation is provided by th…
