The Su–Schrieffer–Heeger (SSH) Hamiltonian has been extended to study the electron–phonon interaction and the electronic structures of the alkali-like metal clusters. The eigen-energy levels of s valence electrons are obtained from a Hückel-like Hamiltonian including the correction of the electron–phonon interaction in the hopping integral, which is proportional to the variable of bond length. The self-consistent equations for electrons and phonons are solved adiabatically through an iteration process. The energy-level structures of an octahedral Cu6 cluster are calculated with variable electron–phonon coupling constant λ to investigate the influence of electron–phonon interaction on the lattice distortion and electronic structures of metal clusters. The size-dependent ionization potential for small Cun clusters are calculated and compared with the experimental results.

The effect of the electron–phonon interaction on the Zeeman splitting of the first excited level of a two-dimensional parabolic quantum dot is studied using the nondiagonal Hartree–Fock variational approximation within the framework of Green's function formalism for the entire range of the electron–phonon interaction strength and arbitrary confinement length. The results are applied to GaAs and CdS quantum dots and it is shown that polaronic interaction can cause a strong size-dependent suppression of the Zeeman splitting in these dots if their sizes are made sufficiently small.
