We present results of numerically exact 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. The Coulomb potential causes the weakly interacting limit to be approached at high density, but gives rise to no qualitatively different behavior, vis-à-vis the superfluid transition, with respect to short-ranged interactions. Our results are of direct relevance to quantitative studies of bipolaron mechanisms of (high-temperature) superconductivity.

Bose单组分等离子体的超导转变温度

我们提出了玻色单组分等离子体的数值精确模拟结果，即粒子之间具有成对库仑相互作用和均匀中和背景的玻色气体。我们计算了二维和三维模型的连续和晶格版本的各种密度下的超导转变温度。库仑势导致在高密度下接近弱相互作用极限，但相对于短程相互作用，相对于超流体转变，不会产生性质不同的行为。我们的结果与（高温）超导双极子机制的定量研究直接相关。
