双色驱动双阱:控制景观的参数透视

Bichromatically driven double well: Parametric perspective of the control landscape

Astha Sethi, Srihari Keshavamurthy

摘要:

我们数值构建并研究了强场存在下的$(ω,2ω)$双色驱动双阱的控制景观。通过将floquet态和初始相空间相干态之间的重叠强度与准能量{ \it,即}的参数运动相关联来获得控制景观。强度级速度相关器“墙”没有控制,强大的领域之间的相对相位的变化下,被认为是在控制景观和涉及混沌floquet状态的多级相互作用。

英文摘要:

We numerically construct and study the control landscape of a $(ω,2ω)$ bichromatically driven double well in the presence of strong fields. The control landscape is obtained by correlating the overlap intensities between the floquet states and an initial phase space coherent state with the parametric motion of the quasienergies {\it i.e.,} intensity-level velocity correlator. "Walls" of no control, robust under variations of the relative phase between the fields, are seen in the control landscape and associated with multilevel interactions involving chaotic floquet states.
