From the Boltzmann equation to the incompressible Navier–Stokes equations on the torus: A quantitative error estimate
We investigate the Boltzmann equation, depending on the Knudsen number, in the Navier-Stokes perturbative setting on the torus. Using hypocoer-civity, we derive a new proof of existence andExpand

Instantaneous Filling of the Vacuum for the Full Boltzmann Equation in Convex Domains
We prove the immediate appearance of a lower bound for mild solutions to the full Boltzmann equation in the torus or a C2 convex domain with specular boundary conditions, under the sole assumption ofExpand

From Boltzmann to incompressible Navier-Stokes in Sobolev spaces with polynomial weight
We study the Boltzmann equation on the $d$-dimensional torus in a perturbative setting around a global equilibrium under the Navier-Stokes linearisation. We use a recent functional analysisExpand

Asymptotic stability of the Boltzmann equation with Maxwell boundary conditions
Abstract In a general C 1 domain, we study the perturbative Cauchy theory for the Boltzmann equation with Maxwell boundary conditions with an accommodation coefficient α in ( 2 / 3 , 1 ] , andExpand

Spectroscopy of calcium deposited on large argon clusters
Abstract:Spectroscopic experiments have been performed, providing emission and excitation spectra of calcium atoms trapped on argon clusters of average size 2 000. The two experimental spectra fallExpand

Spectroscopic manifestations of phase changes in CaArn clusters: finite size effects
Abstract.The finite temperature optical spectroscopy of CaArn clusters in the range 6 ≤ n ≤ 146 is investigated using a Diatomics-In-Molecule (DIM) Hamiltonian and classical parallel tempering MonteExpand

Instantaneous exponential lower bound for solutions to the Boltzmann equation with Maxwellian diffusion boundary conditions
We prove the immediate appearance of an exponential lower bound, uniform in time and space, for continuous mild solutions to the full Boltzmann equation in a $C^2$ convex bounded domain with theExpand

The Boltzmann Equation for a Multi-species Mixture Close to Global Equilibrium
We study the Cauchy theory for a multi-species mixture, where the different species can have different masses, in a perturbative setting on the three dimensional torus. The ultimate aim of this workExpand

Stability of global equilibrium for the multi-species Boltzmann equation in $L^\infty$ settings
We prove the stability of global equilibrium in a multi-species mixture, where the different species can have different masses, on the $3$-dimensional torus. We establish stability estimates inExpand
