【摘要】 本文从非平衡态量子开放体系主方程出发,通过建立复合算子统计平均值运动方程组,并应用推广拉氏变换和采用类似双时格林函数的切断近似方法,提供求解量子统计中不可逆过程的另一种简便途径。更多还原

【Abstract】 Starting from the master equation of the non-equilibrium open quantum,we have iscussed the establishing of the motion equations of the statisticalaverage of the composite perators and the applicatication of the generalizedLaplace transformation and cut-off pproximatjon. Thus we provide an alternat-ive convenient way in solving the irreversible rocesses of quantum stati-stics.更多还原
