Abstract

We present results of first principle numerical simulations of the Bose one-component plasma, i.e., a Bose gas with pairwise Coulomb interactions among particles and a uniform neutralizing background. We compute the superconducting transition temperature for a wide range of densities, in two and three dimensions, for both continuous and lattice versions of the model. Our results are of direct relevance to quantitative studies of bipolaron mechanisms of (high-temperature) superconductivity.
