A Programmable Mechanical Maxwell's Demon. [PDF]
Entropy (Basel), 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 ...

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 ...

Measurement-Based Quantum Thermal Machines with Feedback Control. [PDF]
Entropy (Basel), 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 ...

Maxwell's Demon and the Problem of Observers in General Relativity. [PDF]
Entropy (Basel), 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 ...

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

Maxwell's Demon Walks into Wall Street: Stochastic Thermodynamics Meets Expected Utility Theory. [PDF]
Physical Review Letters, 2023 The interplay between thermodynamics and information theory has a long history, but its quantitative manifestations are still being explored. We import tools from expected utility theory from economics into stochastic thermodynamics.

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 ...

Quantum Maxwell's demon assisted by non-Markovian effects. [PDF]
Physical Review E, 2021 Maxwell's demon is the quintessential example of information control, which is necessary for designing quantum devices. In thermodynamics, the demon is an intelligent being who utilizes the entropic nature of information to sort excitations between ...

Information Gain and Loss for a Quantum Maxwell's Demon. [PDF]
Physical Review Letters, 2018 We use continuous weak measurements of a driven superconducting qubit to experimentally study the information dynamics of a quantum Maxwell's demon. We show how information gained by a demon who can track single quantum trajectories of the qubit can be ...

Extracting Work from Quantum Measurement in Maxwell's Demon Engines. [PDF]
Physical Review Letters, 2017 The essence of both classical and quantum engines is to extract useful energy (work) from stochastic energy sources, e.g., thermal baths. In Maxwell's demon engines, work extraction is assisted by a feedback control based on measurements performed by a ...
