Summary:The effect of electric and magnetic fields on the basic parameters of confined and interface polarons in cylindrical nanowires embedded in a non-polar matrix are studied theoretically for the first time. The analytical expressions for the quasi-one-dimensional Fröhlich polaron self-energy and effective mass are obtained as functions of the wire radius and the strength of the external fields; this can be used in the interpretation of optical phenomena related to polaron motion in cylindrical nanowire when the effect of applied fields competes with the spatial quantum confinement.
