Electric and magnetic optical polaron in quantum dot—Part 1: strong coupling

Abstract

We investigated the influence of electric field and magnetic field on the ground state energy of polaron in spherical semiconductor quantum dot (QD) using a modified Lee Low Pines (LLP) method. The numerical results show the increase of the ground state energy with the increase of the electric field and the decreasing with the magnetic field. The modulation of the electric field, magnetic field and the confinement lengths lead to the control of the decoherence of the system.

“…As a result, the GSE increases with increasing the EF. This result is in agreement with the one of [ 44 ]. In Figure 1 , it is also seen that the GSE decreases with decreasing the RAGCP, displays an asymptotic profile and eventually conforms to a limiting value.…”
