论文摘要
我们提出了一种自适应相技术,用于机械共振的参数冷却。这涉及到机械四元素的检测,然后进行一系列参数调制阶段的周期性控制调整序列。该技术允许以指数的热能损失来制备量子基态,类似于冷阻尼或腔自冷却的情况。在经典和量子制度中,介绍了用于冷却率和最终占用的分析推导。
We propose an adaptive phase technique for the parametric cooling of mechanical resonances. This involves the detection of the mechanical quadratures, followed by a sequence of periodic controllable adjustments of the phase of a parametric modulation. The technique allows the preparation of the quantum ground state with an exponential loss of thermal energy, similarly to the case of cold-damping or cavity self-cooling. Analytical derivations are presented for the cooling rate and final occupancies both in the classical and quantum regimes.
