A methodology of quantum dynamics based on interacting trajectories without reference to any wave function is applied to ultrashort laser ionization of a model hydrogen atom. The pulses are chosen to be so short that the relative phase between the carrier wave and the pulse envelope becomes important. As main results we show that the trajectory-only approach is capable of correctly describing the large amplitude motion and energetics of the laser driven electron and of reproducing carrier-envelope effects onto the photoelectron spectra. It also provides an intuitive picture of the dynamical quantum processes involved.

激光驱动原子电离的量子轨迹研究

在不涉及任何波函数的情况下，基于相互作用轨迹的量子动力学方法被应用于模型氢原子的超短激光电离。选择的脉冲要短到使载波和脉冲包络之间的相对相位变得重要。作为主要结果，我们证明了仅轨迹法能够正确描述激光驱动电子的大幅度运动和高能，并且能够将载流子-包络效应复制到光电子谱上。它还提供了所涉及的动态量子过程的直观描述。
