摘要：

Employing the Fulton-Gouterman transformation (FGT), a non-conventional type of excited states (''exotic'') in exciton-phonon systems has been found recently. These states are characterized by a stiffening of the phononic subsystem. It is shown that the phononic part for these non-conventional exciton-phonon states is well described by squeezed oscillatory functional forms. This can be understood analytically by subjecting the FG Hamiltonian to a Frohlich-type of unitary transformation.
