Abstract
The two-dimensional, one-component logarithmic Coulomb gas is mapped onto a non-Hermitian fermionic field theory. At β = 2, the field theory is free. Correlation functions are calculated and a perturbation theory is discussed for extending to other β. A phase transition is found at the mean-field level at large β. Some results are extended to spaces of constant negative curvature.
