The linear and third order nonlinear optical absorption coefficient and refractive index changes of an elliptic quantum dot have been investigated, using the compact-density matrix formalism and an iterative method. In this regard, the effect of optical intensity, size and geometry of the dot on the
The energy level structure of an interacting system of electrons is analysed. The model chosen describes electrons in a semiconductor quantum dot system, whose energy levels could be accessed via finite-bias transport experiments. We find that the normalized level spacing of the system exhibits sign
## Abstract In the present work, the linear and the thirdβorder nonlinear optical absorption coefficients as well as refractiveβindex changes in a twoβdimensional hexagonal quantum dot with the presence of an impurity are calculated. A matrix diagonalization method is used to calculate energy level
