ENERGY LEVELS OF STRONG COUPLING MAGNETOPOLARON IN QUANTUM WIRE

IntroductionThe strong coupling polaron of bulk type hasbeen studied extensively[1,2 ] . Recently,people hasmuch interest of strong coupling polaron with re-duced dimensionality[3 ] ,especially the two- dimen-sional case[4,5] .T.Yildirim[6] studied the strongcoupling polaron with different dimensionality in aunifying model. S. Hameau et. al.[7] showed thatthe electrons and the longitudinal optical phononsare always in a strong coupling regime and form aneverlasting mixed electron- phonon mode…
