论文摘要
我们在存在Duschinskii旋转的情况下研究了自旋依赖性电子转移。特别是，我们为一个两级模型系统传播动力学，旋转轨道耦合引入了$ e^{iwx} $的州际耦合，这既是位置（x）依赖性且复杂值的位置（x）。我们证明，两级旋转（并因此纠缠的正常模式）与布朗振荡器耦合的两级系统可以产生相对于两级系统耦合到简单移动的和谐振荡器的瞬时自旋极化的明显增加。这些结论对于建模核运动对手性诱导的自旋选择性的影响应该具有重要意义。
We investigate spin-dependent electron transfer in the presence of a Duschinskii rotation. In particular, we propagate dynamics for a two-level model system for which spin-orbit coupling introduces an interstate coupling of the form $e^{iWx}$, which is both position(x)-dependent and complex-valued. We demonstrate that two-level systems coupled to Brownian oscillators with Duschinskii rotations (and thus entangled normal modes) can produce marked increases in transient spin polarization relative to two-level systems coupled to simple shifted harmonic oscillators. These conclusions should have significant relevance for modeling the effect of nuclear motion on chiral induced spin selectivity.
