A quantum system in a condensed phase undergoes strong dissipative processes. The last decades have seen the rise of experimental and theoretical approaches for gaining control over dissipative phenomena. From a theoretical viewpoint it is important to model such processes in a rigorous way. An efficient and accurate method to find control fields is optimal control theory (OCT). In this Letter, a control scheme relying on OCT with time-dependent targets is employed to minimize dissipation, modeled within the surrogate Hamiltonian approach, on adsorbate-surface systems.
凝聚相中的量子系统会经历强烈的耗散过程。在过去的几十年中,人们已经提出了许多实验和理论方法来控制耗散现象。从理论角度来看,以严格的方式对这些过程进行建模非常重要。一种有效的、精确的寻找控制场的方法是最优控制理论(OCT)。在这篇快报中,我们采用了一种基于带有时变目标的 OCT 的控制方案,该方案依赖于替代哈密顿方法,用于最小化吸附剂-表面系统中的耗散,该系统被建模为。
