论文摘要
从时间依赖的角度研究，根据超快相干光谱实验，从时间依赖的角度研究了光收集过程。然而，自然过程发生在不连贯的光线下，这会导致固定状态。可以使用分子哈密顿量的特征性来描述这种固定状态，但是对于逼真的系统，完全的对角线化非常昂贵。我们提出了三种有效的计算方法，以获取围绕哈密顿对角线化系统的固定状态。建立了不一致的扰动，腐蚀和kraus操作员之间的联系。
Light harvesting processes are often computationally studied from a time-dependent viewpoint, in line with ultrafast coherent spectroscopy experiments. Yet, natural processes take place in the presence of incoherent light, which induces a stationary state. Such stationary states can be described using the eigenbasis of the molecular Hamiltonian, but for realistic systems a full diagonalization is prohibitively expensive. We propose three efficient computational approaches to obtaining the stationary state that circumvent system Hamiltonian diagonalization. The connection between the incoherent perturbations, decoherence, and Kraus operators is established.
