Perturbation theory and spectral analysis in quantum mechanics

The research activity of the group is mainly focused on: spectral analisys for non self-adjoint PT symmetric operators of interest in quantum mechanics, in the framework of perturbation theory for linear operators; criteria for the reality of the spectrum; existence criteria for PT phase transition: spontaneous violation of PT symmetry and complex eigenvalues.
