Maxwell's demon and Smoluchowski's trap door.

Maxwell's demon, rectifiers, and the second law: Computer simulation of Smoluchowski's trapdoor

Maxwell's demon assisted thermodynamic cycle in superconducting quantum circuits.

We study a new quantum heat engine (QHE), which is assisted by a Maxwell's demon. The QHE requires three steps: thermalization, quantum measurement, and quantum feedback controlled by the Maxwell demon. We derive the positive-work condition and operation efficiency of this composite QHE. Using controllable superconducting quantum circuits as an example, we show how to construct our QHE. The ess...

Power generator driven by Maxwell's demon

Maxwell's demon is an imaginary entity that reduces the entropy of a system and generates free energy in the system. About 150 years after its proposal, theoretical studies explained the physical validity of Maxwell's demon in the context of information thermodynamics, and there have been successful experimental demonstrations of energy generation by the demon. The demon's next task is to conve...

Computing Entropy: Understanding Maxwell's Demon

In 1871, James Clerk Maxwell proposed that a being, able to measure the microscopic parameters of a physical system and act accordingly, might be able to violate the Laws of Thermodynamics. The being became known as Maxwell's Demon. Investigations conducted over the course of a century have placed well-de ned thermodynamic bounds upon the action of Maxwell's demon. It is the purpose of this wor...

Thermodynamics and efficiency of an autonomous on-chip Maxwell's demon.

In his famous letter in 1870, Maxwell describes how Joule's law can be violated "only by the intelligent action of a mere guiding agent", later coined as Maxwell's demon by Lord Kelvin. In this letter we study thermodynamics of information using an experimentally feasible Maxwell's demon setup based a single electron transistor capacitively coupled to a single electron box, where both the syste...
