The Influences of Spin on the Properties of Bound Magnetopolaron in Quantum Dot

The influences of spin on the properties of weak-coupling bound magnetopolaron in quantum dot have been studied by using a linear combination operator and a unitary transformation method. Considering the effects of spin,the ground state energy of bound magnetopolaron as a function of the confinement length of quantum dot and magnetic field is discussed. The results illustrate that the ground state energy,and spin-up(spin-down)splitting energy of magnetopolaron decrease with increasing the confinement length of quantum dot and increase with increasing the magnetic field when the Coulomb bound potential is definite; The ground state energy and spin-up(spin-down)splitting energy of magnetopolaron decrease with increasing the Coulomb bound potential when the magnetic field is definite.
