预冷策略可实现指数级更快的加热
Pre-Cooling Strategy Allows Exponentially Faster Heating
摘要：
什么是最快的方式来加热一个系统，这是耦合到一个温度控制的烤箱？直观的答案是只使用可用的最热温度。然而，我们表明，通常可以实现指数级更快的加热，并提出了一种策略来找到最佳协议。令人惊讶的是，该协议可以有一个预冷却阶段-在加热之前冷却系统，它大大缩短了加热时间。这种方法可以适用于多体系统，因为我们证明了在二维反铁磁伊辛模型。
英文摘要：
What is the fastest way to heat a system which is coupled to a temperature controlled oven? The intuitive answer is to use only the hottest temperature available. However, we show that often it is possible to achieve an exponentially faster heating, and propose a strategy to find the optimal protocol. Surprisingly, this protocol can have a pre-cooling stage -- cooling the system before heating it shortens the heating time significantly. This approach can be applied to many-body systems, as we demonstrate in the 2D antiferromagnet Ising model.
