Coarse-graining via the fluctuation-dissipation theorem and large-deviation theory
Alberto Montefusco, Mark A. Peletier, Hans Christian Öttinger
The fluctuation-dissipation theorem is a central result in statistical mechanics and is usually formulated for systems described by diffusion processes. In this paper, we propose a…
Probing a critical length scale at the glass transition
Majid Mosayebi, Emanuela Del Gado, Patrick Ilg +1
We give evidence of a clear structural signature of the glass transition, in terms of a static correlation length with the same dependence on the system size which is typical of cr…
Entropic 13 Moment Equations from Boltzmann's Kinetic Equation
Hans Christian Öttinger
We use guiding principles from nonequilibrium thermodynamics to develop an admissible set of 13 moment equations for rarefied gas flows. The main benefits of our thermodynamic appr…
Bridging length and time scales in sheared demixing systems: from the Cahn-Hilliard to the Doi-Ohta model
Asja Jelic, Patrick Ilg, Hans Christian Öttinger
We develop a systematic coarse-graining procedure which establishes the connection between models of mixtures of immiscible fluids at different length and time scales. We start fro…
Dissipative electromagnetism from a nonequilibrium thermodynamics perspective
Asja Jelic, Markus Hütter, Hans Christian Öttinger
Dissipative effects in electromagnetism on macroscopic scales are examined by coarse graining the microscopic Maxwell equations with respect to time. We illustrate a procedure to d…
Systematic coarse graining: "Four lessons and a caveat" from nonequilibrium statistical mechanics
Hans Christian Öttinger
With the guidance offered by nonequilibrium statistical thermodynamics, simulation techniques are elevated from brute-force computer experiments to systematic tools for extracting…
