The Cyclotron Resonance Characteristics of Magnetopolaron and the Average Number of Optical Phonons in the Quantum Rods

Based on the method of the Huybrechts linear combination operator,the cyclotron resonance characteristics of electron-longitudinal optical phonons strongly-coupling magnetopolaron on the ground-state under parabolic confinement potential in the quantum rods within a magnetic field were studied,and the variation law of the cyclotron resonance frequency,the average optical phonon number of magnetopolaron change with cyclotron frequency of magnetic field,the electron-phonon coupling strength,aspect ratio of quantum rods and confinement strength are derived by using the Lee-Low-Pines unitary transformation and various techniques.Numerical results show that the average number of optical phonon and cyclotron resonance frequency of magnetopolaron will increase with the growth of the cyclotron frequency of magnetic field,while the electron-phonon coupling strength and the confinement strength of quantum rods decrease with the increase of aspect ratio of quantum rods.
