Spectral analysis of a semiclassical random walk associated to a general confining potential
Thomas Normand
We consider a semiclassical random walk with respect to a probability measure associated to a potential with a finite number of critical points. We recover the spectral results fro…

Spectral asymptotics and metastability for the linear relaxation Boltzmann equation
Thomas Normand
We consider the linear relaxation Boltzmann equation in a semiclassical framework. We construct a family of sharp quasimodes for the associated operator which yields sharp spectral…
