Berezinskii-Kosterlitz-Thouless-type transitions in d=2 quantum O(2) and O(2)xO(2) nonlinear sigma models
C. A. Hooley, S. T. Carr, J. M. Fellows +1
We discuss the d=2 quantum O(2)xO(2) nonlinear sigma model as a low-energy theory of phase reconstruction near a quantum critical point. We first examine the evolution of the Berez…

Unbinding of giant vortices in states of competing order
Jonathan M. Fellows, Sam T. Carr, Christopher A. Hooley +1
We consider a two-dimensional system with two order parameters, one with O(2) symmetry and one with O(), near a point in parameter space where they couple to become a single O($…
