Generalized hydrodynamics and the classical hydrodynamic limit
, 2018 This work is concerned with our recently developed formalism of non-equilibrium thermodynamics. This formalism extends the classical irreversible thermodynamics which leads to classical thermodynamics and can not describe physical phenomena with long relaxations. With the extended theory, we obtain a generalized hydrodynamic system which can be used to

A Model of Solar Equilibrium: The Hydrodynamic Limit [PDF]
The Astrophysical Journal, 2019 Abstract Helioseismology has revealed the internal density and rotation profiles of the Sun. Yet, knowledge of its magnetic fields and meridional circulation is confined much closer to the surface, and latitudinal entropy gradients are below detectable limits.

Connecting Pre-Thermal and Hydrodynamizing Attractors With Adiabatic Hydrodynamization [PDF]
EPJ Web of ConferencesThe far-from equilibrium dynamics of the pre-hydrodynamic quarkgluon plasma (QGP) formed in heavy ion collisions can be characterized by distinct stages, during each of which the system loses some memory of its initial condition, until only the ...

Hydrodynamic Limit of the Gross-Pitaevskii Equation [PDF]
Communications in Partial Differential Equations, 2014 We study dynamics of vortices in solutions of the Gross-Pitaevskii equation $i \partial_t u = Δu + \varepsilon^{-2} u (1 - |u|^2)$ on $\mathbb{R}^2$ with nonzero degree at infinity. We prove that vortices move according to the classical Kirchhoff-Onsager ODE for a small but finite coupling parameter $\varepsilon$.

Entropy-limited hydrodynamics: a novel approach to relativistic hydrodynamics [PDF]
Computational Astrophysics and Cosmology, 2017 AbstractWe present entropy-limited hydrodynamics (ELH): a new approach for the computation of numerical fluxes arising in the discretization of hyperbolic equations in conservation form. ELH is based on the hybridisation of an unfiltered high-order scheme with the first-order Lax-Friedrichs method.

Magnetotransport of Weyl semimetals with ℤ2 topological charge and chiral anomaly
Journal of High Energy Physics, 2019 We calculate the magnetoconductivity of the Weyl semimetal with ℤ2 topological charge and chiral anomaly utilizing the recently developed hydrodynamic theory.

On the Hydrodynamic Limit of the Enskog Equation
Publications of the Research Institute for Mathematical Sciences, 1998 The Enskog equation in the hydrodynamie limit is investigated. If the Knudsen number ε and the scale of diameter a of the hard sphere particles are of the same order,

Stationary Solutions to the Boltzmann Equation in the Hydrodynamic Limit [PDF]
Annals of PDE, 2017 Despite its conceptual and practical importance, the rigorous derivation of the steady incompressible Navier-Stokes-Fourier system from the Boltzmann theory has been {an} outstanding {open problem} for general domains in 3D. We settle this open question in {the} affirmative, in the presence of a small external field and a small boundary temperature ...

Nonlinear hydrodynamic theory for a dilute gas-solid suspension [PDF]
EPJ Web of ConferencesA second-order hydrodynamic theory is proposed for a dilute gas-solid suspension within the framework of the inelastic Boltzmann equation. A distribution function based on 14-hydrodynamic fields is used to calculate the colisional source terms that are ...
