Quantum thermodynamics: Microscopic foundations of entropy and of entropy generation by irreversibility

open access: yesAtti della Accademia Peloritana dei Pericolanti : Classe di Scienze Fisiche, Matematiche e Naturali, 2008
What is the physical significance of entropy? What is the physical origin of irreversibility? Do entropy and irreversibility exist only for complex and macroscopic systems?

Advances in Josephson Junction Materials and Processes Toward Practical Quantum Computing

open access: yesAdvanced Science, EarlyView.
Emerging materials for quantum computing, including crystalline materials, two‐dimensional van der Waals materials, two‐dimensional electron gas systems, ferromagnets, and unconventional (e.g., d‐wave) superconductors, offer opportunities to engineer next‐generation Josephson junctions.

Dynamic Supercooled Crystal–Gels for Ultrafast, Reversible Mechanical Adaptative Materials

open access: yesAdvanced Science, EarlyView.
A dynamic supercooled crystal–gel mimics starfish tissue by storing non‐equilibrium energy in a metastable liquid. A gentle touch triggers templated crystallization, producing a 2596‐fold stiffness increase with negligible volume change. The lattice disintegrates reversibly under humidity or warmth.

Programmable Budding and Fission of Janus Polymersomes for Tunable Cargo Release

open access: yesAngewandte Chemie, EarlyView.
A thermodynamic framework establishes the conditions for the formation of kinetically stable Janus polymersomes using a solvent‐assisted strategy. Osmotic stress subsequently drives their membrane remodeling from reversible budding to controlled fission.

Transport of Heat and Charge in Electromagnetic Metrology Based on Nonequilibrium Statistical Mechanics

open access: yesEntropy, 2009
Current research is probing transport on ever smaller scales. Modeling of the electromagnetic interaction with nanoparticles or small collections of dipoles and its associated energy transport and nonequilibrium characteristics requires a detailed ...

Wave thermalization and its implications for nonequilibrium statistical mechanics

open access: yes, 2017
Understanding the rich spatial and temporal structures in nonequilibrium thermal environments is a major subject of statistical mechanics. Because universal laws, based on an ensemble of systems, are mute on an individual system, exploring nonequilibrium

pyDMS: A Python package for the determination of physics‐informed dual‐mode sorption (DMS) parameters

open access: yesAIChE Journal, EarlyView.
Abstract Sorption in glassy polymer membranes is commonly modeled with the dual‐mode sorption (DMS) model. Fitting the DMS model to sorption isotherms presents challenges, as multiple parameter sets may prove satisfactory. This work presents pyDMS, an open‐source Python package for the computation of DMS parameters obtained via a physics‐informed ...

Nonequilibrium Statistical Mechanics for Adiabatic Piston Problem [PDF]

open access: yesJournal of Statistical Physics, 2014
We consider the dynamics of a freely movable wall of mass $M$ with one degree of freedom that separates a long tube into two regions, each of which is filled with rarefied gas particles of mass $m$. The gases are initially prepared at equal pressure but different temperatures, and we assume that the pressure and temperature of gas particles before ...

SRB states and nonequilibrium statistical mechanics close to equilibrium

open access: yes, 1997
Nonequilibrium statistical mechanics close to equilibrium is studied using SRB states and a formula for their derivatives with respect to parameters. We write general expressions for the thermodynamic fluxes (or currents) and the transport coefficients ...

A Unifying Approach to Self‐Organizing Systems Interacting via Conservation Laws

open access: yesAdvanced Intelligent Discovery, EarlyView.
The article develops a unified way to model and analyze self‐organizing systems whose interactions are constrained by conservation laws. It represents physical/biological/engineered networks as graphs and builds projection operators (from incidence/cycle structure) that enforce those constraints and decompose network variables into constrained versus ...
