西拉德发动机是麦克斯韦“恶魔”的精髓,它可以利用信息从热浴中提取功。我们提出了第一个完整的量子分析的SZE,并推导出一个解析表达式的量子SZE包含一个任意数量的分子,其中它是至关重要的插入或删除的壁作为一个合法的热力学过程的过程中进行的量子力学工作。我们发现,更多(更少)的工作,可以提取玻色子(费米)的SZE由于全同粒子的不可分割性。
The Szilard engine (SZE) is the quintessence of Maxwell's demon, which can extract the work from a heat bath by utilizing information. We present the first complete quantum analysis of the SZE, and derive an analytic expression of the quantum-mechanical work performed by a quantum SZE containing an arbitrary number of molecules, where it is crucial to regard the process of insertion or removal of a wall as a legitimate thermodynamic process. We find that more (less) work can be extracted from the bosonic (fermionic) SZE due to the indistinguishability of identical particles.
