Accuracy of energy measurement and reversible operation of a microcanonical Szilard engine.
In a recent paper [Vaikuntanathan and Jarzynski, Phys. Rev. E 83, 061120 (2011)], a model was introduced whereby work could be extracted from a thermal bath by measuring the energy of a particle that was thermalized by the bath and manipulating the potential of the particle in the appropriate way, depending on the measurement outcome. If the extracted work is Wextracted and the work Werasure ne...
متن کاملElectrical Maxwell Demon and Szilard Engine Utilizing Johnson Noise, Measurement, Logic and Control
We introduce a purely electrical version of Maxwell's demon which does not involve mechanically moving parts such as trapdoors, etc. It consists of a capacitor, resistors, amplifiers, logic circuitry and electronically controlled switches and uses thermal noise in resistors (Johnson noise) to pump heat. The only types of energy of importance in this demon are electrical energy and heat. We also...
متن کاملDemons : Maxwell ’ S Demon , Szilard ’ S Engine and Landauer ’ S Erasure – Dissipation Laszlo
This talk addressed the following questions in the public debate at HoTPI: (i) energy dissipation limits of switches, memories and control; (ii) whether reversible computers are possible, or does their concept violate thermodynamics; (iii) Szilard’s engine, Maxwell’s demon and Landauer’s principle: corrections to their exposition in the literature; (iv) whether Landauer’s erasure– dissipation p...
متن کاملQuantum Szilard engine.
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 ...
