陷阱中弱相互作用玻色子的近似二次量子化方法
Weakly-Interacting Bosons in a Trap within Approximate Second Quantization Approach
摘要：
本文将Bogoliubov的理论推广到简谐势阱中弱相互作用玻色气体的情形。得到了一组非线性矩阵方程，使哈密顿量的对角化成为可能。用微扰解计算了模型系统的能量和凝结分数，以说明该方法的适用性。
英文摘要：
The theory of Bogoliubov is generalized for the case of a weakly-interacting Bose-gas in harmonic trap. A set of nonlinear matrix equations is obtained to make the diagonalization of Hamiltonian possible. Its perturbative solution is used for the calculation of the energy and the condensate fraction of the model system to show the applicability of the method.
