Maxwell’s Demon in Quantum Mechanics [PDF]

open access: yesEntropy, 2020
Maxwell’s Demon is a thought experiment devised by J. C. Maxwell in 1867 in order to show that the Second Law of thermodynamics is not universal, since it has a counter-example. Since the Second Law is taken by many to provide an arrow of time, the

N-States Continuous Maxwell Demon [PDF]

open access: yesEntropy, 2023
Maxwell’s demon is a famous thought experiment and a paradigm of the thermodynamics of information. It is related to Szilard’s engine, a two-state information-to-work conversion device in which the demon performs single measurements and extracts work ...

Hidden Dissipation and Irreversibility in Maxwell’s Demon [PDF]

open access: yesEntropy, 2022
Maxwell’s demon is an entity in a 150-year-old thought experiment that paradoxically appears to violate the second law of thermodynamics by reducing entropy without doing work.

A Programmable Mechanical Maxwell’s Demon [PDF]

open access: yesEntropy, 2019
We introduce and investigate a simple and explicitly mechanical model of Maxwell’s demon—a device that interacts with a memory register (a stream of bits), a thermal reservoir (an ideal gas) and a work reservoir (a mass that can be lifted or ...

Information-to-work conversion by Maxwell’s demon in a superconducting circuit quantum electrodynamical system [PDF]

open access: yesNature Communications, 2018
Maxwell’s demon is a hypothetical character that uses information about a system to reduce its entropy, highlighting the link between information and thermodynamic entropies. Here the authors experimentally realise a Maxwell's demon controlling a quantum

Landauer’s Principle in a Quantum Szilard Engine without Maxwell’s Demon [PDF]

open access: yesEntropy, 2020
Quantum Szilard engine constitutes an adequate interplay of thermodynamics, information theory and quantum mechanics. Szilard engines are in general operated by a Maxwell’s Demon where Landauer’s principle resolves the apparent paradoxes ...

Measurement-Based Quantum Thermal Machines with Feedback Control [PDF]

open access: yesEntropy, 2023
We investigated coupled-qubit-based thermal machines powered by quantum measurements and feedback. We considered two different versions of the machine: (1) a quantum Maxwell’s demon, where the coupled-qubit system is connected to a detachable single ...

All Shook Up: Fluctuations, Maxwell’s Demon and the Thermodynamics of Computation

open access: yesEntropy, 2013
The most successful exorcism of Maxwell’s demon is Smoluchowski’s 1912 observation that thermal fluctuations would likely disrupt the operation of any molecular-scale demonic machine.

Maxwell’s Demon and the Problem of Observers in General Relativity [PDF]

open access: yesEntropy, 2018
The fact that real dissipative (entropy producing) processes may be detected by non-comoving observers (tilted), in systems that appear to be isentropic for comoving observers, in general relativity, is explained in terms of the information theory ...

Conditioning, Correlation and Entropy Generation in Maxwell’s Demon

open access: yesEntropy, 2013
Maxwell’s Demon conspires to use information about the state of a confined molecule in a Szilard engine (randomly frozen into a state subspace by his own actions) to derive work from a single-temperature heat bath.
