The Demon in a Vacuum Tube

Entropy, 2013
In the present paper, several issues concerning the second law of thermodynamics, Maxwell’s demon and Landauer’s principle are dealt with. I argue that if the demon and the system on which it operates without dissipation of external energy are made of ...

Alternative experimental ways to access entropy production

Physical Review Research, 2021
We theoretically derive and experimentally compare several different ways to access entropy production in a quantum process under feedback control. We focus on a bipartite quantum system realizing an autonomous Maxwell's demon scheme reported by Najera ...

Does Observation Create Reality? [PDF]

, 2020
It has been suggested that the locality of information transfer in quantum entanglement indicates that reality is subjective, meaning that there is an innate inseparability between the physical system and the conscious mind of the observer.

Efficiency fluctuations and noise induced refrigerator-to-heater transition in information engines [PDF]

, 2019
Understanding noisy information engines is a fundamental problem of non-equilibrium physics, particularly in biomolecular systems agitated by thermal and active fluctuations in the cell.

Conditioning, Correlation and Entropy Generation in Maxwell’s Demon

Entropy, 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.

Experimental Rectification of Entropy Production by Maxwell's Demon in a Quantum System. [PDF]

Physical Review Letters, 2016
Maxwell's demon explores the role of information in physical processes. Employing information about microscopic degrees of freedom, this "intelligent observer" is capable of compensating entropy production (or extracting work), apparently challenging the

Normal metal - superconductor tunnel junction as a Brownian refrigerator [PDF]

, 2007
Thermal noise generated by a hot resistor (resistance $R$) can, under proper conditions, catalyze heat removal from a cold normal metal (N) in contact with a superconductor (S) via a tunnel barrier. Such a NIS junction acts as Maxwell's demon, rectifying

Quantum Fluctuation Theorems

, 2018
Recent advances in experimental techniques allow one to measure and control systems at the level of single molecules and atoms. Here gaining information about fluctuating thermodynamic quantities is crucial for understanding nonequilibrium thermodynamic ...

Maxwell's Demon and Data Compression

, 2011
In an asymmetric Szilard engine model of Maxwell's demon, we show the equivalence between information theoretical and thermodynamic entropies when the demon erases information optimally. The work gain by the engine can be exactly canceled out by the work

Membrane Transport, Molecular Machines, and Maxwell's Demon

ChemSystemsChem
The spontaneous generation of transmembrane gradients is an important fundamental research goal for artificial nanotechnology. The active transport processes that give rise to such gradients directly mirror the famous Maxwell’s Demon thought experiment ...
