摘要

Similar to the bosonization method in one dimension,we divide the electron operators in phase space into two component operators,and study three-dimensional homogeneous electron gas with a strong correlation effect.We apply this method to calculate the pair distribution function g(r =0,rs) and the renormalization coefficient of the one-electron Green's function Z (kF) (ZF),and show that it has great advantages of succinctness and effciency for studying one-and three-dimensional systems with a strong correlation effect.This method can be applied to investigate interaction quenches in ultracold atomic gases.
