论文摘要
我们指出，在超导体中，可能存在围绕静态电荷的电气和冷凝水场的局部量子激发，这不能简单地解释为筛选电荷的基态以及一定数量的大量光子。这是通过有效的金茨堡 - 兰道模型中的一对分离的静态电荷的晶格蒙特卡洛计算来说明的。
We point out that in superconductors there may exist localized quantum excitations of the electric and condensate fields surrounding a static charge, which cannot be interpreted as simply the ground state of the screened charge plus some number of massive photons. This is illustrated via a lattice Monte Carlo calculation of the energy spectrum of a pair of separated static charges in an effective Ginzburg-Landau model of superconductivity.
