非平衡密度矩阵的超算子耦合集团方法

Superoperator coupled cluster method for nonequilibrium density matrix

Alan A. Dzhioev, D. S. Kosov

摘要:

我们发展了一种求解Lindblad主方程描述的非平衡开放多体量子系统的超算符耦合集团方法。该方法具有普适性,适用于相互作用的费米子、玻色子及其混合物系统。我们提出了一个一般的理论,并考虑其应用的问题,通过系统的电子-声子关联的量子输运。对微扰理论和非平衡组态相互作用理论计算的结果进行了评估。

英文摘要:

We develop a superoperator coupled cluster method for nonequilibrium open many-body quantum systems described by the Lindblad master equation. The method is universal and applicable to systems of interacting fermions, bosons or their mixtures. We present a general theory and consider its application to the problem of quantum transport through the system with electron-phonon correlations. The results are assessed against the perturbation theory and nonequilibrium configuration interaction theory calculations.
