The Algorithm A chieve of Entanglement of Heisenberg Model Using Fortran Program and the Eliminating Methods of Random Datas

介绍Fortran程序下计算海森堡模型纠缠度的算法实现及计算结果中所出现的随机数据的消除方法,为研究者们在各种普适计算中提高计算结果的准确度方面提供一些借鉴方法。研究方法:在利用置换群方法产生能量矩阵和N粒子纯态的纠缠度定义的情况下,使用Fortran软件编程计算海森堡模型的纠缠度,对计算结果中的非预期随机数据采用物理法及更换(matlab代替fortran)软件编程计算的方法进行消除。研究结果:使用物理法消除随机数据费时费力,使用更换软件编程计算以消除随机数据的方法效果较好。

The algorithm achieve of entanglement of heisenberg model using fortran program and the eliminating methods of the random datas are introduced. Searchers may get some reference methods of improving the accuracy of the calculating re-suits in research work.The studying methods are the following. In the situations of energy matrix formed by the method of per- mutation group and the definition of entanglement of N particle and pure state, The entanglement of heisenberg model is cal- culated using fortran program. The unexpected random datas of the calculating results are eliminated using physical laws and replacement of software programming.The studying results are the following. It takes long time and too much energy that the random datas are eliminated using physical laws.There is good effect when the random datas are ehminated using madab soft-ware instead of fortran software.
