Vortex confinement transitions in the modified Goldstone model
The modified XY model is a variation of the XY model extended by a half-period term, exhibiting a rich phase structure. As the Goldstone model, also known as the linear O(2) model, can be obtained as a continuum and regular model for the XY model, we define the modified Goldstone model as that of th...
