摘要
We study the temperature effects of the vibrational frequency, the ground state energy and the ground state binding energy of the strong-coupling magnetopolaron in an anisotropic quantum dot. The vibrational frequency, the ground state energy and the ground state binding energy are expressed as functions of the temperature, the cyclotron frequency of a magnetic field and the electron-phonon coupling strength by using linear combination operator and unitary transformation methods. It is found that these quantities will increase with increasing temperature and cyclotron frequency of a magnetic field. The vibrational frequency and the ground state binding energy are increasing functions of the electron-phonon coupling strength, whereas the ground state energy is an decreasing one of it.
