A Structure-Preserving Effective Linear Approximation of the Quantum Boltzmann Collision Operator
Shuang Hu, Bo Lin, Zhenning Cai
We construct a structure-preserving effective linear approximation of the quantum Boltzmann collision operator for Bose and Fermi gases in the normal phase. For variable hard-spher…

Global well-posedness of the linearized R13 moment equations with Onsager boundary conditions
Shuang Hu, Bo Lin, Huini Liu +1
This paper establishes the global well-posedness of the linearized regularized 13-moment (R13) equations for rarefied gas flows. We first derive an entropy inequality for the syste…
