Study of Theoretical Ground State Energy Effect of the Electron-Phonon Interaction in Semiconductor QD

Abstract

- In this paper using the correlated quantum threaded by Aharonov -Bohm flux in the presence of electron -phonon interaction and Rashba spin- orbit coupling. The quantum ring is modified by Hulstein- Hubbard-Rashba Hamiltonian. The ground state energy  is evaluated by performing the conventional Long-Firsov transformation by diagonalization of the effective Hamiltonian in the limit of mean field approximation. If ground state energy is differentiate with respect to flux obtained the persistent current. We also studied the variation of persistent current with temperature in presence of and also in presence of Rashba interaction
