Hausdroff公式的自动代数展开及其应用

AUTOMATED ALGEBRIC EXTENSION OF HAUSDROFF FORMULA AND ITS APPLICATION

报道了用代数语言ＲＥＤＵＣＥ模拟Ｈａｕｓｄｒｏｆｆ公式叠代展开过程的计算机程序ＳＩＭＨＡＵＳ．并通过实例叙述了用ＳＩＭＨＡＵＳ程序处理自旋体系在复杂哈密顿作用下的计算机辅助分析过程．为有关这方面的脉冲序列的分析和设计提供了一种新方法．

A program SIMHAUS had been developed to simulate the algebric iterative process of the Hausdroff formula. The program can be used to analyse the evolution of density operator under complex Hamiltonian and to improve pulse sequence. Authors illustrate the application of the program to solve the evolution of I2S spin system during the isotropic mixing process.
