Pi-electrons in an aromatic ring chiral molecule can rotate clockwise or counterclockwise by applying a linearly polarized ultrashort laser pulse even though the electronic state has no degeneracy and no angular momentum character. We have proposed the principle of a multidimensional ultrashort-time switching device by laser control of pi-electron induced ring current and the current-induced magnetic field. (P)-2,2'-biphenol having two benzene rings was taken as a model chiral molecule. For practical use, we made simulations of time-dependent coherent ring currents by taking into account effects of interactions between pi-electron and molecular vibrations or heat bath modes in condensed phases.

芳环手性分子的电子态不具有简并性和角动量特征，但在施加线偏振超短激光脉冲的情况下，电子可以顺时针或逆时针旋转。提出了一种利用激光控制pi-电子感应环电流和电流感应磁场的多维超短时开关器件的原理。以具有两个苯环的(P)-2,2'-双酚为模型手性分子。在实际应用中，我们通过考虑π电子和分子振动或凝聚相热浴模式之间相互作用的影响，模拟了时间相关的相干环电流。
