论文摘要
通过使用Boltzmann动力学方程，这是一种半古典方法，已经在磷烯中研究了磁性棘轮效应。使用紧密结合模型得出了稳定平行磁场中磷烯的哈密顿量。我们考虑在AC激光场和空间反转不对称的情况下，磁场对非线性动力学的影响。我们已经表明，对于各向异性2D材料和磷烯，棘轮电流对三种不同的光极化具有响应：线性极化的光，圆形偏振光和未铝光。
The magnetic ratchet effect has been studied in phosphorene by the use of the Boltzmann kinetic equation that is a semi-classical approach. The Hamiltonian of phosphorene in a steady parallel magnetic field is derived using the tight-binding model. We consider the effect of the magnetic field on non--linear dynamics in the presence of an ac laser field and spatial inversion asymmetry. We have shown that for anisotropic 2D materials and phosphorene, the ratchet current has the response to three different light polarizations: linearly polarized light, circularly polarized light, and unpolarized light.
