We will present a detailed investigation of intersubband transitions process in core-multi shells quantum dots. The confined wave functions and eigenenergies of electrons in quantum dots have been calculated under the effective-mass approximation by solving a three-dimensional Schrodinger equation. Excellent dependence is found between size effects, time relaxation and degenerate four wave mixi...

We present new links between some remarkable martingales found in the study of the Binary Search Tree or of the bisection problem, looking at them on the probability space of a continuous time binary branching process.

We compute the boundary entropies for the allowed boundary conditions of the SU (2)-invariant principal chiral model at level k = 1. We used the reflection factors determined in ref.[27]. As a by-product we obtain some miscellaneous results such as the ground-state energy for mixed boundary conditions as well as the degeneracies of the Kondo model in the underscreened and exactly screened cases...

The spectrum of eigenenergies of a quantum integrable system whose hamil-tonian depends on a single parameter shows degeneracies (crossings) when the parameter varies. We derive a semiclassical expression for the density of crossings in the plane energy-parameter, that is the number of crossings per unit of energy and unit of parameter, in terms of classical periodic orbits. We compare the resu...

I discuss the physics case of the standard Neutrino Factory facility coupled to an iron detector to exploit the so-called ‘Golden-Channel’. The performance of the facility is impressive, although it is not free from degeneracies arising from a combination of physics and instrumental limitations. Nevertheless, one could explore at great depth the parameter of the leptonic mixing matrix as well a...

We study exact representations for offset curves and surfaces, for equal-distance curves and surfaces, and for fixedand variable-radius blending surfaces. The representations are myekeme of nonlinear equationn that define the curves and surfaces as natural projections from a bigherdimeneional space into &space. We show that the systems derived by-naively trsnalating the geometric constrainb def...
