Effects of spin on the properties of strong-coupled bound magnetopolaron in quantum dot

On the basis of the Huybrechts' strong-coupled model, the Tokuda modified linear combination operator method and the unitary transformation method are used to study the properties of the strong-coupled bound magnetopolaron considering the influence of the spin in the quantum dot (QD). The expressions for the ground-state energy of the polaron as a function of the confinement length of the QD, the magnetic field and the coulomb bound potential are derived. Numerical calculation is performed and the results illustrate that the ground-state energy of the magnetopolaron is composed of three parts. Finally, we discuss the contribution of the spin to the ground-state energy, the self-energy, the Landau ground-state energy and the coulomb bound energy of the bound magnetopolaron and find the spin has very important effects on the properties of the polaron.
