Nevertheless , the results provided by these methods are all inaccurate . in this thesis , in order to overcome the drawbacks , we reconstruct the bose - hubbard model hamiltonian with differential realization of bosonic operators , and investigate the exact numerical solutions of the one dimension bose - hubbard model . firstly , energy matrices can be generated rapidly by using a mathematica package 首先利用mathematica程序快速生成模型在各種位型下能量矩陣,然后將該程序的結果直接作為其它矩陣對角化程序的輸入而求出該模型在相應位型下的本征值和相應的本征波函數。
