Ground States of a Two-Dimensional Charged-Boson System
Abstract
The ground state of a two-dimensional charged-boson system is investigated over the range of densities 1 somewhat < Rs somewhat < 10 in the self-consistent field approximation: Rsub s = Sqrt(1/((a sub o) sq rho pi)), where a is the Bohr radius and rho is the number density. Starting with numerical self-consistent calculations of the static structure factor, the elementary excitation, pair-correlation functions, pressure and ground-state energy are evaluated. These results are compared with those of the two- dimensional and three-dimensional systems obtained from other methods. The ground-state energy is given sub as E0 = -1.2918 Rs-2/3 + 0.03, which improves the result from the ring-diagram approximation.
