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

Maxwell’s Demon Is Foiled by the Entropy Cost of Measurement, Not Erasure
FoundationsI dispute the conventional claim that the second law of thermodynamics is saved from a “Maxwell’s demon” by the entropy cost of information erasure and show that instead it is measurement that incurs the entropy cost.

N-States Continuous Maxwell Demon [PDF]
Entropy, 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 ...

Conditional Action and Imperfect Erasure of Qubits [PDF]
Entropy, 2021 We consider state changes in quantum theory due to “conditional action” and relate these to the discussion of entropy decrease due to interventions of “intelligent beings” and the principles of Szilard and Landauer/Bennett.

Entropic Probability and Context States [PDF]
EntropyIn a previous paper, we introduced an axiomatic system for information thermodynamics, deriving an entropy function that includes both thermodynamic and information components.

A model of entropy production [PDF]
Scientific ReportsA key tenet of the Transactional Interpretation of Quantum Mechanics is the idea that photon absorption localizes the absorbing material system. In doing so, it measures the location of the absorber and hence reduces information entropy which in turn ...

Photonic Maxwell’s Demon: Feed-forward methods for photonic thermodynamic tasks [PDF]
EPJ Web of Conferences, 2022 Maxwell’s Demon is at the heart of the interrelation between quantum information processing and thermodynamics. In this thought experiment, a demon extracts work from two thermal baths at equilibrium by gaining information about them at the single ...

Thermodynamics of quantum measurement and Maxwell's demon's arrow of time [PDF]
Physical Review A, 2022 We discuss the thermodynamic aspects of a single qubit based device, powered by weak quantum measurements, and feedback controlled by a quantum Maxwell’s demon.

Maxwell's demon-like nonreciprocity by non-Hermitian gyrotropic metasurfaces
Physical Review Research, 2021 We show that Maxwell's demon-like nonreciprocity can be supported in a class of non-Hermitian gyrotropic metasurfaces in the linear regime. The proposed metasurface functions as a transmission-only Maxwell's demon operating at a pair of photon energies ...
