Weyl law for semi-classical resonances with randomly perturbed potentials
Johannes Sjoestrand
In this work we consider semi-classical Schrödinger operators with potentials supported in a bounded strictly convex subset of with smooth boundary. Letting…

Resolvent estimates for elliptic quadratic differential operators
Michael Hitrik, Johannes Sjoestrand, Joe Viola
Sharp resolvent bounds for non-selfadjoint semiclassical elliptic quadratic differential operators are established, in the interior of the range of the associated quadratic symbol.
