Development of optimal control simulation and its applications

我们已经开发了量子最优控制模拟，可以处理分子和激光场之间的非线性相互作用。（1）将模拟应用于氮分子的取向控制。从最佳脉冲的周期平均强度的功率谱，我们提出了一个频率网络机制，有效地连接几个最低的旋转状态，通过拉曼跃迁，以实现高度的对齐。(2)In的CO分子的取向控制，我们已经表明了两步控制的有效性，其中的取向脉冲出现之前的取向脉冲。(3)We进一步扩展了模拟，以明确包括激光脉冲的偏振。它被应用于同时的振转控制，目的是创造一个振转波包，不能实现的线偏振脉冲。

We have developed quantum optimal control simulation that can treat nonlinear interactions between a molecule and laser fields.(1)The simulation is applied to the alignment control of a nitrogen molecule. From the power spectrum of the cycle-averaged intensity of the optimal pulse, we have proposed a frequency network mechanism that effectively connects a few lowest rotational states through Raman transitions to achieve a high degree of alignment.(2)In the orientation control of a CO molecule, we have shown the effectiveness of a two-step control, in which an alignment pulse appear prior to an orientation pulse.(3)We further extended the simulation to explicitly include the polarization of a laser pulse. It was applied to the simultaneous rovibrational control with the aim of creating a rovibrational wave packet that cannot be achieved by a linearly polarized pulse.
