Effects of temperature and magnetic field on the ground state binding energy of the strong coupling magneto-polaron in an RbC1 asymmetrical semi-exponential quantum well

摘要

The ground state binding energy (E-b) and the mean number of LO phonons (N) of the strong-coupling magneto-polaron (SCMP) in an asymmetrical semi-exponential quantum well (ASEQW) are studied theoretically. Temperature (T) effects on E-b and N are acquired with the quantum statistics theory (QST). By using the Lee-Low-Pines unitary transformation (LLPUT) and linear combination operation method (LCOM), the variations of E-b and N with T and omega(c) of magnetic field are discussed. The investigated results indicate that both T and omega(c) have great influence on E-b and N of LO phonons.
