Comparative Analysis of Fluctuations in Viscoelastic Stress: A Comparison of the Temporary Network and Dumbbell models

Arturo Winters, Hans Christian Öttinger, Jan Vermant

Traditionally, stress fluctuations in flowing and deformed materials are overlooked, with an obvious focus on average stresses in a continuum mechanical approximation. However, the…

Conserved Currents for the Gauge-Field Theory with Lorentz Symmetry Group

Hans Christian Öttinger

For the Yang-Mills-type gauge-field theory with Lorentz symmetry group, we propose and verify an explicit expression for the conserved currents in terms of the energy-momentum tens…

Dissipation in spin chains using quantized nonequilibrium thermodynamics

Massimo Borrelli, Hans Christian Öttinger

We investigate the open dynamics of a chain of interacting spins using the quantized version of the GENERIC equation from classical out-of-equilibrium thermodynamics. We focus on b…

Mathematical structure and physical content of composite gravity in weak-field approximation

Hans Christian Öttinger

The natural constraints for the weak-field approximation to composite gravity, which is obtained by expressing the gauge vector fields of the Yang-Mills theory based on the Lorentz…

A framework of nonequilibrium statistical mechanics. II. Coarse-graining

Alberto Montefusco, Mark A. Peletier, Hans Christian Öttinger

For a given thermodynamic system, and a given choice of coarse-grained state variables, the knowledge of a force-flux constitutive law is the basis for any nonequilibrium modeling.…

Natural Hamiltonian formulation of composite higher derivative theories

Hans Christian Öttinger

If a higher derivative theory arises from a transformation of variables that involves time derivatives, a tailor-made Hamiltonian formulation is shown to exist. The details and adv…

Stability analysis for a thermodynamically consistent model of relativistic fluid dynamics

Laura Stricker, Hans Christian Öttinger

The search for thermodynamic admissibility moreover reveals a fundamental difference between liquids and gases in relativistic fluid dynamics, as the reversible convection mechanis…

Structure-preserving integrators for dissipative systems based on reversible-irreversible splitting

Xiaocheng Shang, Hans Christian Öttinger

We study the optimal design of numerical integrators for dissipative systems, for which there exists an underlying thermodynamic structure known as GENERIC (general equation for th…

Deformation of inherent structures to detect long-range correlations in supercooled liquids

Majid Mosayebi, Emanuela Del Gado, Patrick Ilg +1

We propose deformations of inherent structures as a suitable tool for detecting structural changes underlying the onset of cooperativity in supercooled liquids. The non-affine disp…

Canonical Distribution Functions in Polymer Dynamics: I. Dilute Solutions of Flexible Polymers

Patrick Ilg, Iliya V. Karlin, Hans Christian Öttinger

The quasi--equilibrium or maximum entropy approximation is applied in order to derive constitutive equations from kinetic models of polymer dynamics. It is shown in general and ill…

Minimal entropic kinetic models for simulating hydrodynamics

Santosh Ansumali, Iliya V. Karlin, Hans Christian Öttinger

We derive minimal discrete models of the Boltzmann equation consistent with equilibrium thermodynamics, and which recover correct hydrodynamics in arbitrary dimensions. A simple an…

Generating moment equations in the Doi model of liquid-crystalline polymers

P. Ilg, I. V. Karlin, H. C. Öttinger

We present a self-consistent method for deriving moment equations for kinetic models of polymer dynamics. The Doi model [M. Doi, J.Polymer. Sci., Polym. Phys. Ed. 19, 229 (1981)] o…

Thermodynamically admissible form for discrete hydrodynamics

Pep Español, Hans Christian Öttinger

We construct a discrete model of fluid particles according to the GENERIC formalism. The model has the form of Smoothed Particle Hydrodynamics including correct thermal fluctuation…
