Based on the self-consistent Hartree–Fock approximation, the nonstationary equation is obtained for the one-particle wave function describing the Bose–Einstein condensate in a rarefied gas of spin-zero bosons. A rarefied gas of bosons is exposed to the static external field, which ensures its finite ground state. The derived equation allows one to correctly determine the ground state energy in the stationary case.

玻色-爱因斯坦凝聚物的单粒子波函数的非平稳方程

基于自洽Hartree-Fock逼近，对于描述自旋零玻色子稀疏气体中的玻色-爱因斯坦凝聚物的单粒子波函数，获得了非平稳方程。稀有的玻色子气体会暴露在静态外部场中，从而确保其有限的基态。推导的方程式使人们能够正确地确定静止情况下的基态能量。
