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,然後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徵值和相應的本徵波函數。The use of wave packet to analyze the dynamics of quantum mechanical systems is an increasingly important method to the study of the classical - quantum correspondence. using the quantum gaussian wave packet analysis method, we calculate the autocorrelation function of the rectangular billiard, the peak positions of the autocorrelation function match well with the periods of the classical periodic orbits, which show that the period of the classical orbits can be produced by the time - dependent quantum wave packet method. we also discuss wave packet revivals and fractional revivals in the rectangular billiard, the results show that there are exact revival for all wave packet at each revival time. we find additional cases of exact revivals with short revival times for zero - momentum wave packets initially located at special symmetry point inside the billiard
利用波包分析量子力學體系的動力學行為在研究經典和量子的對應關系方面越來越成為一個非常重要的方法.利用高斯波包分析方法,我們計算了矩形彈子球體系的自關聯函數,自關聯函數的峰和經典周期軌道的周期符合的很好,這表明經典周期軌道的周期可以通過含時的量子波包方法產生.我們還討論了矩形彈子球的波包回歸和波包的部分回歸,計算結果表明在每一個回歸時間,波包出現精確的回歸.對于動量為零的波包,初始位置在彈子球內部的特殊對稱點處,出現一些時間比較短的附加的回歸
