A Modified Szilard's Engine: Measurement, Information, and Maxwell's Demon [PDF]
Entropy, 2004 : Using an isolated measurement process, I've calculated the effect measurement has on entropy for the multi-cylinder Szilard engine. This calculation shows that the system of cylinders possesses an entropy associated with cylinder total energy states ...

Entropy Distribution in a Quantum Informational Circuit of Tunable Szilard Engines [PDF]
Entropy, 2019 This paper explores the possibility of extending the existing model of a single-particle Quantum Szilard Engine to take advantage of some features of quantum information for driving typical mechanical systems. It focuses on devices that output mechanical

Partially observable Szilárd engines [PDF]
New Journal of Physics, 2022 Almost a century ago, Leo Szilárd replaced Maxwell’s ‘demon’ by machinery. The resulting information engine concept laid the foundation for studying the physical nature of information. Szilárd reduced the demon’s role to mapping an observable onto a work

Nonequilibrium thermodynamics of a superconducting Szilard engine [PDF]
New Journal of PhysicsWe implement a Szilard engine using a 2-bit logical unit consisting of inductively coupled quantum flux parametrons—Josephson-junction superconducting circuits with applications in both the classical and quantum information processing regimes.

Biochemical Szilard engines for memory-limited inference [PDF]
New Journal of Physics, 2019 By designing and leveraging an explicit molecular realisation of a measurement-and-feedback-powered Szilard engine, we investigate the extraction of work from complex environments by minimal machines with finite capacity for memory and decision-making ...

Experimental realization of a Szilard engine with a single electron [PDF]
Proceedings of the National Academy of Sciences of the United States of America, 2014 Significance A Maxwell demon makes use of information to convert thermal energy of a reservoir into work. A quantitative example is a thought experiment known as a Szilard engine, which uses one bit of information about the position of a thermalized molecule in a box to extract k B

Bosonic Szilard engine assisted by Feshbach resonances [PDF]
Physical Review A, 2018 It was recently found that the information-to-work conversion in a quantum Szilard engine can be increased by using a working medium of bosons with attractive interactions. In the original scheme, the work output depends on the insertion and removal position of an impenetrable barrier that acts like a piston, separating the chambers of the engine. Here,

Szilard Engines and Information-Based Work Extraction for Active Systems [PDF]
Physical Review Letters, 2022 The out of equilibrium nature of active systems can be exploited for the design of information-based engines. We design two types of an active Szilard engine that use a Maxwell daemon to extract work from an active bath composed of non-interacting Active Brownian Particles (ABPs).

Non-equilibrium dynamics of the piston in the Szilard engine [PDF]
EPL (Europhysics Letters), 2019 We consider a Szilard engine in one dimension, consisting of a single particle of mass $m$, moving between a piston of mass $M$, and a heat reservoir at temperature $T$. In addition to an external force, the piston experiences repeated elastic collisions with the particle.

Econophysics and the Landauer Principle: A Redefinition of Economic Temperature [PDF]
EntropyA redefinition of key notions in econophysics based on the Landauer principle is proposed. Marginal economic temperature is defined via the economic Landauer principle and is proportional to the minimal monetary cost associated with erasing or ...
