“…In Reference [22] the polaron energy in QDs was calculated using a LLP approach and it was found that the polaronic effect is more pronounced for small dot sizes. In Reference [17], using a modified LLP approach, the number of phonons around the electron, and the size of the polaron for the ground state, and for the first two excited states is calculated via the adiabatic approach. Many other works have been done on polaron and molecules considering the effect of electric field OE23 26 and magnetic field OE27 .…”

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.

We investigate the influence of the electric field and magnetic fields on the ground state energy of a polaron in a spherical semiconductor quantum dot (QD) using the 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 electronphonon coupling constant, and the decrease with the magnetic field and the longitudinal confinement length. It is also seen that the temperature is an increasing function of the cyclotron frequency and the coupling constant whereas it decreases with the electric field strength. The modulation of the electric field, the magnetic field and the confinement length leads to the control of decoherence in the system.

The Optical Polaron in Spherical Quantum Dot Confinement

Abstract: The problem of a polaron in quantum dot is retrieved using a modified LLP approach. The modification is intended to interpolate between the strong- and the weak-coupling limits of the problem. The polaronic effect is found to be more important for small dot sizes.
