Summary:Effects of temperature and electron–phonon coupling strength on vibrational frequency, the ground state energy and the ground state binding energy of strong-coupling polaron in an asymmetric quantum dot have been investigated by using linear combination operator and unitary transformation methods. It is found that vibrational frequency and ground state binding energy are increasing functions of temperature and electron–phonon coupling strength, whereas the ground state energy increases with increasing temperature and decreasing electron–phonon coupling strength.
