Multiscale Thermodynamics: Energy, Entropy, and Symmetry from Atoms to Bulk Behavior
Ralph V. Chamberlin, Michael R. Clark, Vladimiro Mujica +1
Here we investigate how local properties of particles in a thermal bath influence the thermodynamics of the bath. We utilize nanothermodynamics, based on two postulates: that small…
An introduction to nanothermodynamics: Thermal equilibrium for heterogeneous and finite-sized systems
Ralph V. Chamberlin, Michael R. Clark, Vladimiro Mujica +1
The theory of small-system thermodynamics was originally developed to extend the laws of thermodynamics to length scales of nanometers. Here we review this "nanothermodynamics," an…
Energy localization and excess fluctuations from long-range interactions in equilibrium molecular dynamics
Ralph V. Chamberlin, Vladimiro Mujica, Sergei Izvyekov +1
Molecular Dynamics (MD) simulations of standard systems of interacting particles ("atoms") give excellent agreement with the equipartition theorem for the average energy, but we fi…
Fluctuation theorems and 1/f noise from a simple matrix
Ralph V. Chamberlin, Sumiyoshi Abe, Bryce F. Davis +2
Here we present a model for a small system combined with an explicit entropy bath that is comparably small. The dynamics of the model is defined by a simple matrix, M. Each row of…
Lindbladian operators, von Neumann entropy and energy conservation in time-dependent quantum open systems
Congjie Ou, Ralph V. Chamberlin, Sumiyoshi Abe
The Lindblad equation is widely employed in studies of Markovian quantum open systems. Here, firstly, a simple result is presented on the time evolution of the non Neumann entropy…
The Big World of Nanothermodynamics
Ralph V. Chamberlin
Nanothermodynamics extends standard thermodynamics to facilitate finite-size effects on the scale of nanometers. A key ingredient is Hill's subdivision potential that accommodates…
