Query: Dimensionality Effects on the Su-Schrieffer-Heeger Model   A low order diagrammatic study of the dimension dependent
Su-Schrieffer-Heeger model Hamiltonian in the weak electron-phonon coupling
regime is presented. Exact computation of both the charge carrier effective
mass and the electron spectral function shows that electrons are good
quasiparticles in the antiadiabatic limit but new features emerge in the
adiabatic and intermediate regime, where the phonons and the electrons compare
on the energy scale. Here we find: i) a sizeable mass enhancement over the bare
band value, ii) the appearance of many transition peaks in the band bottom
spectral function together with a growing loss of spectral weight at larger
{\it e-ph} couplings. The onset of a polaronic state is favoured in two
dimensions.
