The ground-state energy of bound polaron was obtained with strong electron-LO-phonon coupling using a variational method of the Pekar type in a parabolic quantum dot (QD). Quantum transition occurred in the quantum system due to the electron-phonon interaction and the influence of temperature. That

A Landau-Pekar variational theory is employed to obtain the ground and the first excited state binding energies of an electron bound to a Coulomb impurity in a polar semiconductor quantum dot (QD) with parabolic confinement in both two and three dimensions. It is found that the binding energy increa
The ground-state energy of bound polaron in quantum confinement has been calculated by using N-variational parameters to Feynmans approximation action. The method of calculation is based on the Jensen-Feynman inequality which provides an upper bound for the ground-state energy of the polaron in quan
