Random Walks and Anderson Localisation in a Three-Dimensional Class C Network Model
M. Ortuño, A. M. Somoza, J. T. Chalker
We study the disorder-induced localisation transition in a three-dimensional network model that belongs to symmetry class C. The model represents quasiparticle dynamics in a gaples…
Excitations of the One Dimensional Bose-Einstein Condensates in a Random Potential
V. Gurarie, G. Refael, J. T. Chalker
We examine bosons hopping on a one-dimensional lattice in the presence of a random potential at zero temperature. Bogoliubov excitations of the Bose-Einstein condensate formed unde…
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…
Structural phase transitions in geometrically frustrated antiferromagnets
Timothy E. Saunders, John T. Chalker
We study geometrically frustrated antiferromagnets with magnetoelastic coupling. Frustration in these systems may be relieved by a structural transition to a low temperature phase…
