The dynamics of quantum resonances, their energies and their widths, are investigated by means of time-dependent unitary and non-unitary transformations of the Hamiltonian. The aim of the change of representation of the Schrodinger equation is to shape the wave function of the resonances to transform non-square integrable wave functions into localized square-integrable functions. The approach has two advantages: first, it closely relates the energy of the resonances to their dynamics, second… Expand
