The gauge theory dual of the bilayer XY model with second order Josephson coupling
Pye Ton How, Sungkit Yip
We formulate a duality transformation for a bilayer XY model where the layers are coupled by second order Josephson effect, which favors inter-layer phase difference of either …

Broken time reversal symmetry vestigial state for a two-component superconductor in two spatial dimensions
P. T. How, S. K. Yip
We consider the vestigial phase with broken time-reversal symmetry above the superconducting transition temperature of a two-component superconductor in two spatial dimensions. We…
