论文摘要
我们在存在完美反射边界的情况下引入了一种相对论量子类似物的新模型。单个量子量充当与无质量量子标量场相互作用的工作物质，边界遵守了Dirichlet条件。量子真空通过iNRUH效果充当热浴。我们观察到，量子量的响应函数通过反射边界的存在显着修改。从相关函数的结构来看，我们发现三种不同的情况出现了，即中间边界状态，近边界状态和远端边界制度。正如预期的那样，当反射边界变为无穷大时，远端边界状态中的相关性接近了Unruh Quantum Otto Engine（UQOE）的相关性。反射边界的效果通过降低量子的临界激发概率和发动机的工作输出来体现。尽管工作输出降低，但即使在边界存在的情况下，发动机的效率也没有改变。
We introduce a new model of relativistic quantum analogue of the classical Otto engine in the presence of a perfectly reflecting boundary. A single qubit acts as the working substance interacting with a massless quantum scalar field, with the boundary obeying the Dirichlet condition. The quantum vacuum serves as a thermal bath through the Unruh effect. We observe that the response function of the qubit gets significantly modified by the presence of the reflecting boundary. From the structure of the correlation function, we find that three different cases emerge, namely, the intermediate boundary regime, the near boundary regime, and the far boundary regime. As expected, the correlation in the far boundary regime approaches that of the Unruh quantum Otto engine (UQOE) when the reflecting boundary goes to infinity. The effect of the reflecting boundary is manifested through the reduction of the critical excitation probability of the qubit and the work output of the engine. In spite of the reduced work output, the efficiency of the engine remains unaltered even in the presence of the boundary.
