论文摘要
当耦合的电子核动力学受到强floquet驾驶时，出现的近刺象近似发生了很大的分解。在本文中，我们得出了一个Fokker-Planck方程，以用电子摩擦为Floquet驱动的系统来描述非绝热分子动力学。我们首先为驱动的电子核动力学提供了Floquet量子古典liouville方程（QCL）的新推导。然后，我们将Floquet Qcle转换为具有明确形式的摩擦力和随机力形式的Fokker-Planck方程。我们根据Floquet Green的功能重新铸造了电子摩擦，以便我们可以明确评估电子摩擦。我们表明，即使在实现的汉密尔顿的平衡处，Floquet电子摩擦张量也表现出反对称术语，这表明即使没有任何旋转孔子耦合，也有Floquet驱动的非出生的OppenHeeimer动力学中的Lorentz样力。
When the coupled electron-nuclear dynamics are subjected to strong Floquet driving, there is a strong breakdown of the Born-Oppenheimer approximation. In this article, we derive a Fokker-Planck equation to describe non-adiabatic molecular dynamics with electronic friction for Floquet driven systems. We first provide a new derivation of the Floquet quantum-classical Liouville equation (QCLE) for driven electron-nuclear dynamics. We then transform the Floquet QCLE into a Fokker-Planck equation with explicit forms of frictional force and random force. We recast the electronic friction in terms of Floquet Green's functions such that we can evaluate the electronic friction explicitly. We show that the Floquet electronic friction tensor exhibits antisymmetric terms even at equilibrium for real-valued Hamiltonian, suggesting that there is a Lorentz-like force in Floquet driven non-Born Oppenheimer dynamics even without any spin-orbit couplings.
