麦克斯韦妖可解模型中的功和信息处理

Work and information processing in a solvable model of Maxwell's demon

Dibyendu Mandal, Christopher Jarzynski

摘要:

我们描述了一个极小模型的自主麦克斯韦恶魔,一个设备,提供工作整流热波动,同时写入信息到内存寄存器。我们精确地求解了模型的稳态行为,并构造了它的相图。我们发现,我们的设备也可以作为一个“兰道尔橡皮擦”,使用外部提供的工作,以消除信息从内存寄存器。通过揭示一个明确的,透明的操作机制,我们的模型提供了一个简单的范式,调查热力学的信息处理的小系统。

英文摘要:

We describe a minimal model of an autonomous Maxwell demon, a device that delivers work by rectifying thermal fluctuations while simultaneously writing information to a memory register. We solve exactly for the steady-state behavior of our model, and we construct its phase diagram. We find that our device can also act as a "Landauer eraser", using externally supplied work to remove information from the memory register. By exposing an explicit, transparent mechanism of operation, our model offers a simple paradigm for investigating the thermodynamics of information processing by small systems.
