Abstract The expression of the ground-state energy of the electron coupled simultaneously with a Coulomb potential and a longitudinal-optical phonon field in parabolic quantum dots and wires is derived within the framework of Feynman variational path integral theory. We obtain a general result with arbitrary electron-phonon coupling constant, Coulomb binding parameters, and confining potential strength, which could be used for further numerical calculation of polaron properties. Moreover, it is shown that all the previous path-integral formulae for free polarons, bound polarons, and polarons confined in parabolic quantum dots and wires can be recovered in the present formalism.
