Counter-examples to the fractal Weyl law for semiclassical resonances

Jean-Francois Bony, Setsuro Fujiie, Thierry Ramond +1

Under general assumptions, the numbers of semiclassical resonances is known to be bounded from above by a negative power of which is given by the fractal dimension of the trapp…

An example of resonance instability

Jean-Francois Bony, Setsuro Fujiie, Thierry Ramond +1

We construct a semiclassical Schrödinger operator such that the imaginary part of its resonances closest to the real axis changes by a term of size when a real compactly suppor…

Applications of resonance theory without analyticity assumption

Jean-Francois Bony, Laurent Michel, Thierry Ramond

We prove that the results in scattering theory that involve resonances are still valid for non-analytic potentials, even if the notion of resonance is not defined in this setting.…

Barrier-top resonances for non globally analytic potentials

Jean-Francois Bony, Setsuro Fujiie, Thierry Ramond +1

We give the semiclassical asymptotic of barrier-top resonances for Schrödinger operators on , , whose potential is everywhere and analytic a…

Resonances for homoclinic trapped sets

Jean-Francois Bony, Setsuro Fujiie, Thierry Ramond +1

We study semiclassical resonances generated by homoclinic trapped sets. First, under some general assumptions, we prove that there is no resonance in a region below the real axis.…

Non-real Eigenvalues for PT-Symmetric Double Wells

Amina Benbernou, Naima Boussekkine, Nawal Mecherout +2

We study small, PT-symmetric perturbations of self-adjoint double-well Schrödinger operators in dimension . We prove that the eigenvalues stay real for a very small pertur…
