Spectrum of the product of Toeplitz matrices with application in probability
Bernard Bercu, Jean-Francois Bony, Vincent Bruneau
We study the spectrum of the product of two Toeplitz operators. Assume that the symbols of these operators are continuous and real-valued and that one of them is non-negative. We p…
Dynamical resonances and SSF singularities for a magnetic Schroedinger operator
Maria Angélica Astaburuaga, Philippe Briet, Vincent Bruneau +2
We consider the Hamiltonian of a 3D spinless non-relativistic quantum particle subject to parallel constant magnetic and non-constant electric field. The operator has infin…
Semiclassical Resonances of Schrödinger operators as zeroes of regularized determinants
Jean-Marc Bouclet, Vincent Bruneau
We prove that the resonances of long range perturbations of the (semiclassical) Laplacian are the zeroes of natural perturbation determinants. We more precisely obtain factorizatio…
