dc.description.abstractLinear and nonlinear absorption coefficients of two electron spherical quantum clot (QD) with parabolic potential are investigated in this paper. Wave functions and energy eigenvalues of the 1s(2), 1s1p, 1s1d and 1s1f electronic states have been computed by using an optimization approach, which is a combination of Quantum Genetic Algorithm (QGA) and Hartree-Fock Roothaan (I-IFR) method. It is found that the strength of S -> P transition is stronger than P -> D and D -> F transitions. Also the peak positions and amplitudes of the absorption coefficients are sensitive to the electron spin. It should be noted that the peak positions and amplitudes of absorption coefficients are strongly dependent on the parabolic potential. Additionally, dot radius, impurity charge, incident optical intensity and relaxation time have a great influence on the linear and nonlinear absorption coefficients.
