Abstract
The properties of the strong-coupling magnetopolaron in a parabolic quantum dot are studied for the first time using an improved linear combination operator method. The relation between the vibration frequency, the interaction energy and the effective mass of the strong-coupling magnetopolaron in a parabolic quantum dot with the magnetic field, the confinement strength and the electron-phonon coupling strength were derived. Numerical calculations for the RbCl crystal, for example, are performed and the results show that the vibration frequency, the effective mass and the interaction energy of the strong-coupling magnetopolaron in a parabolic quantum dot will increase quickly with decreasing effective confinement length of the quantum dot. Those attributed to interesting quantum size effects will appear.
