We plan to theoretically study the use of quantum feedback control for engineering dissipative environments with tailored properties for systems of ultracold atoms in optical lattices. For this purpose continuous measurements of the system via the off-resonant scattering of photons from a tailored probe beam into a cavity mode shall be considered and a focus will lie on the combination of feedback control with Floquet engineering. Based on this approach, we will design and test strategies for cooling, dissipative state preparation, mimicking thermal baths, suppressing Floquet heating, studying heat transport and ordering in non-equilibrium steady states, and inducing non-trivial relaxation dynamics.

我们计划从理论上研究量子反馈控制在工程耗散环境中的应用，这些环境具有光学晶格中超冷原子系统的定制特性。为此，应考虑将定制探针光束的光子非谐振散射到腔模式中，对系统进行连续测量，并将重点放在反馈控制与Floquet工程的结合上。基于这种方法，我们将设计和测试冷却，耗散状态制备，模拟热浴，抑制Floquet加热，研究非平衡稳态中的热传递和有序，以及诱导非平凡松弛动力学的策略。
