联系信息与热力学的Maxwell Demon模型

A Maxwell demon model connecting information and thermodynamics

Peiyan Peng, Changkui Duan

摘要:

在过去的十年中,已经提出了几个理论上的麦克斯韦恶魔模型,表现出诸如制冷、以信息为代价做功等效应,并且已经进行了一些实验来实现这些效应。在这里,我们提出了一个模型与两个级别的恶魔,信息表示的一个序列的位,和两个热源。恶魔与哪个水库互动取决于钻头。如果信息是纯的,一个存储器将被冷冻,另一方面,如果温差大,信息可以被擦除。这样一个系统的真正的例子进行了讨论。

英文摘要:

In the past decade several theoretical Maxwell's demon models have been proposed exhibiting effects such as refrigerating, doing work at the cost of information, and some experiments have been done to realise these effects. Here we propose a model with a two level demon, information represented by a sequence of bits, and two heat reservoirs. Which reservoir the demon interact with depends on the bit. If information is pure, one reservoir will be refrigerated, on the other hand, information can be erased if temperature difference is large. Genuine examples of such a system are discussed.
