Emergence of Gaussian fields in noisy quantum chaotic dynamics
Maxime Ingremeau, Martin Vogel
We study the long time Schrödinger evolution of Lagrangian states on a compact Riemannian manifold of negative sectional curvature. We consider two models of semicla…

Improved bounds for eigenfunctions under random perturbations in negative curvature
Maxime Ingremeau, Martin Vogel
It has been known since the work of AvakumovÃc, Hörmander and Levitan that, on any compact smooth Riemannian manifold, if , then $\|Ï_λ\|_{L^\infty} \leq…

Pseudospectra and eigenvalue asymptotics for disordered non-selfadjoint operators in the semiclassical limit
Martin Vogel
The purpose of this note is to review some recent results concerning the pseudospectra and the eigenvalues asymptotics of non-selfadjoint semiclassical pseudo-differential operator…
