Maxwell's Demon at work: Two types of Bose condensate fluctuations in power-law traps

open access: yes, 1997
After discussing the key idea underlying the Maxwell's Demon ensemble, we employ this idea for calculating fluctuations of ideal Bose gas condensates in traps with power-law single-particle energy spectra.

A Friendly Guide to Exorcising Maxwell’s Demon

open access: yesPRX Quantum
The birth, life, and death of Maxwell’s demon provoked a profound discussion about the interplay between thermodynamics, computation, and information. Even after its resolution, the demon continues to inspire a multidisciplinary field.

Fermionic reaction coordinates and their application to an autonomous Maxwell demon in the strong coupling regime [PDF]

open access: yes, 2018
We establish a theoretical method which goes beyond the weak coupling and Markovian approximations while remaining intuitive, using a quantum master equation in a larger Hilbert space.

Resilient Flow Regimes in the Rio Grande—Río Bravo Basin

open access: yesRiver Research and Applications, EarlyView.
ABSTRACT Water is essential for human development and is an indispensable resource for economic activity and a country's growth. However, current water practices, along with increasing land‐use change, climate change, and agricultural practices, have significantly altered the hydrological cycle and water availability.

Weaponizing Nature, Naturalizing Violence: Anthropologies of Ecofascism

open access: yesAmerican Anthropologist, Volume 128, Issue 1, Page 224-236, March 2026.
ABSTRACT After decades of denial and obstruction, the global Right is increasingly willing to acknowledge that climate change is a threat to lives and lifeways everywhere. Moreover, some seize on the specter of ecological collapse to advance fascistic politics.

Information and flux in a feedback controlled Brownian ratchet

open access: yes, 2008
We study a feedback control version of the flashing Brownian ratchet, in which the application of the flashing potential depends on the state of the particles to be controlled.

Autonomous out-of-equilibrium Maxwell's demon for controlling the energy fluxes produced by thermal fluctuations.

open access: yesPhysical Review E, 2020
An autonomous out-of-equilibrium Maxwell's demon is used to reverse the natural direction of the heat flux between two electric circuits kept at different temperatures and coupled by the electric thermal noise. The demon does not process any information,

Quantum Carnot Bound from Petz Recovery Maps

open access: yesAdvanced Physics Research, Volume 5, Issue 2, February 2026.
A quantum bound (ηP$\eta_P$, the Petz Limit) is derived for the efficiency (η$\eta$) of a heat engine utilizing two‐level quantum systems (qubits) as the working substance. This limit, based on Petz recovery maps, is stricter than the classical Carnot limit (ηC$\eta_C$) for irreversible cycles.

Language Individuation and Marker Words: Shakespeare and His Maxwell's Demon. [PDF]

open access: yesPLoS ONE, 2013
BACKGROUND:Within the structural and grammatical bounds of a common language, all authors develop their own distinctive writing styles. Whether the relative occurrence of common words can be measured to produce accurate models of authorship is of ...

An autonomous and reversible Maxwell's demon

open access: yes, 2013
Building on a model introduced by Mandal and Jarzynski [Proc. Natl. Acad. Sci. U. S. A., {\bf 109}, (2012) 11641], we present a simple version of an autonomous reversible Maxwell's demon. By changing the entropy of a tape consisting of a sequence of bits
