Energy levels of impurity magnetopolarons in parabolic quantum wires

A variational perturbative method is established to calculate the energy levels of impurity magnetopolarons in parabolic quantum wires for arbitrary values of electron-phonon coupling constant α, Rydberg constant R, frequency of the parabolic potential ω and cyclotron frequency ω c . Numerical resul...

Description
Summary:A variational perturbative method is established to calculate the energy levels of impurity magnetopolarons in parabolic quantum wires for arbitrary values of electron-phonon coupling constant α, Rydberg constant R, frequency of the parabolic potential ω and cyclotron frequency ω c . Numerical results are derived and discussed for the energies of the ground state and the first excited state.
