Conformal field theory and the hot phase of three-dimensional U(1) gauge theory

13 May 2019 Caselle Michele Nada Alessandro Panero Marco Vadacchino Davide

We study the high-temperature phase of compact U(1) gauge theory in 2+1 dimensions, comparing the results of lattice calculations with analytical predictions from the conformal-field-theory description of the low-temperature phase of the bidimensional XY model. We focus on the two-point correlation functions of probe charges and the field-strength operator, finding excellent quantitative agreement with the functional form and the continuously varying critical indices predicted by conformal field theory...
