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…
PT-symmetry and Schrödinger operators. The double well case
Nawal Mecherout, Naima Boussekkine, Thierry Ramond +1
We study a class of PT-symmetric semiclassical Schrödinger operators, which are perturbations of a selfadjoint one. Here, we treat the case where the unperturbed operator has a dou…
PT symétrie et puits de potentiel
Naima Boussekkine, Nawal Mecherout
In this work we consider PT-symmetric perturbations of a self-adjoint semi-classical Schrödinger operator on the real axis in the case of a simple potential well. We assume that th…
