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

## 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
The linear and nonlinear optical absorptions of a two-electron quantum dot are studied by using the matrix diagonalization method. The oscillator strength of the transition is calculated within the effective-mass approximation, along with the linear and the third-order nonlinear and the total optica
In this paper we review our recent study of coherent electronic properties of coupled twodimensional quantum dot arrays using numerical exact-diagonalization methods on a Mott-Hubbard type correlated tight-binding model. We predict the existence of a novel kind of persistent current in a two-dimensi
