Rough Axisymmetric Euler Dynamics: Global Energy Compactness and Kinetic Passage Across Regularity Breakdown

Gi-Chan Bae, Hongxu Chen, Chanwoo Kim

We establish global energy compactness for rough three-dimensional axisymmetric Euler flow without swirl and use it to construct hydrodynamic limits of collisional kinetic equation…

Measure-valued free-energy minimizers for trapped bosons with repulsive Coulomb interaction

Gi-Chan Bae, Jinmyoung Seok

We study a free-energy minimization problem for a trapped semiclassical Bose gas with repulsive Coulomb self-interaction. Because the bosonic entropy density has zero recession slo…

Quantitative Closure Analysis toward Ideal Fluids

Gi-Chan Bae, Chanwoo Kim

We establish the incompressible low--Mach/high--Reynolds limit for the Boltzmann equation for a broad class of initial data, without recourse to any asymptotic expansion. Exploitin…

On the comparison between phenomenological and kinetic theories of gas mixtures with applications to flocking

Gi-Chan Bae, Seung-Yeal Ha, Gyuyoung Hwang +1

We study the compression between the phenomenological and kinetic models for a mixture of gases from the viewpoint of collective dynamics. In the case in which constituents are Eul…

Numerical schemes for a multi-species quantum BGK model

Gi-Chan Bae, Marlies Pirner, Sandra Warnecke

This work is devoted to the numerical implementation of the quantum Bhatnagar- Gross-Krook (BGK) model for gas mixtures consisting of classical and quantum particles (fermions, bos…

Large amplitude problem of BGK model: Relaxation to quadratic nonlinearity

Gi-Chan Bae, Gyounghun Ko, Donghyun Lee +1

Bhatnagar-Gross-Krook (BGK) equation is a relaxation model of the Boltzmann equation which is widely used in place of the Boltzmann equation for the simulation of various kinetic f…
