We present a systemic theoretical study of the electronic properties of the quantum dots inserted in quantum dot infrared photodetectors (QDIPs). The strain distribution of three different shaped quantum dots (QDs) with a same ratio of the base to the vertical aspect is calculated by using the short-range valence-force-field (VFF) approach. The calculated results show that the hydrostatic strai...

The dynamics of a globally coupled, logistic map lattice is explored over a parameter plane consisting of the coupling strength, varepsilon, and the map parameter, a. By considering simple periodic orbits of relatively small lattices, and then an extensive set of initial-value calculations, the phenomenology of solutions over the parameter plane is broadly classified. The lattice possesses many...

We consider the 3D Gross-Pitaevskii equation \begin{equation}\nonumber i\partial_t \psi +\Delta \psi+(1-|\psi|^2)\psi=0 \text{ for } \psi:\mathbb{R}\times \mathbb{R}^3 \rightarrow \mathbb{C} \end{equation} and construct traveling waves solutions to this equation. These are of form $\psi(t,x)=u(x_1,x_2,x_3-Ct)$ with a velocity $C$ order $\varepsilon|\log\varepsilon|$ small parameter $\varepsilon...

At each iteration of a Block Coordinate Descent method one minimizes an approximation the objective function with respect to generally small set variables subject constraints in which these are involved. The unconstrained case and simple were analyzed recent literature. In this paper we address problem block not and, moreover, they defined by global sets equations inequations. A general algorit...
