费米子影响超算符:发展模拟费米子环境对具有任意宇称对称性的量子系统的影响的方法的规范推导

The Fermionic influence superoperator: a canonical derivation for the development of methods to simulate the influence of a Fermionic environment on a quantum system with arbitrary parity symmetry

摘要:

我们提出了一个影响超算符的正则推导,它产生了一个线性耦合到一个初始处于热平衡的费米量子系统的约化动力学。我们使用这种形式主义推导出一个广义Lindblad主方程(在马尔可夫极限)和一个广义版本的分层运动方程有效的任意奇偶对称条件下,重要的是正确评价系统的关联函数和光谱。

英文摘要:

We present a canonical derivation of an influence superoperator which generates the reduced dynamics of a Fermionic quantum system linearly coupled to a Fermionic environment initially at thermal equilibrium. We use this formalism to derive a generalized-Lindblad master equation (in the Markovian limit) and a generalized version of the hierarchical equations of motion valid in arbitrary parity-symmetry conditions, important for the correct evaluation of system correlation functions and spectra.
