处于凝聚相的量子系统经历强耗散过程。在过去的几十年里，实验和理论方法的兴起，以获得对耗散现象的控制。从理论的角度来看，重要的是以严格的方式模拟这些过程。最优控制理论（OCT）是一种有效而精确的求解控制场的方法。在这封信中，依赖于OCT与时间相关的目标的控制方案，以尽量减少耗散，替代哈密顿方法内建模，吸附物表面系统。
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.
