MAGNETIC POLARON IN A CYLINDRICAL QUANTUM-WIRE

The energy spectrum of an electron in a cylindrical wire with an infin itely high barrier at the boundary and with a parabolic potential insi de the wire is obtained. The transformation of the spectrum with incre asing oscillator (Omega) and magnetic (omega(H)) frequencies is invest igated. The polaron corrections arising in the electronic energy level s and the translational effective mass as a result of the interaction with bulk and interface modes are obtained by the perturbation-theory method in the Wigner-Brillouin approximation, and their dependences on the magnetic field are determined. The magnetic polaron resonance is studied and the splitting of the resonance polaron levels is calculate d. (C) 1996 American Institute of Physics.
