Abstract
We study the equation of state of three-dimensional compact U(1) gauge theory on the lattice by means of numerical simulations, and discuss the implications of our results for the spectrum of the theory, in connection with previous results from the literature. We also compare our findings to the case of non-Abelian gauge theories and comment on the continuum limit.
