Description
Summary:The critical properties of \(N\)-color London model are studied in \(d=2+1\) dimensions. The model is dualized to a theory of \(N\) vortex fields interacting through a Coulomb and a screened potential. The model with N=2 shows two anomalies in the specific heat. From the critical exponents \(\alpha\) and \(\nu\), the mass of the gauge field, and the vortex correlation functions, we conclude that one anomaly corresponds to an {\it inverted} \xy fixed point, while the other corresponds to a \xy fixed point. There are \(N\) fixed points, namely one corresponding to an inverted \xy fixed point, and \(N-1\) corresponding to neutral \xy fixed points. This represents a novel type of quantum fluid, where superfluid modes arise out of charged condensates.
