The consequences of the Clifford structure of Nambu mechanics with more than one multiplet are presented. The only case considered is that in which S triplets are present

We solve the Klein-Gordon equation in the presence of a spatially one-dimensional Woods-Saxon potential. The bound state solutions are derived. The pair creation mechanism and the antiparticle bound state are discussed.

We discuss the mechanism of production of positrons and electrons by a spatially homogeneous time-dependent electric field whose amplitude vanishes for large values of time. Using the Hamiltonian diagonalization technique, we compute the density of particles created as a function…

A new heat operator with N = 1 supersymmetry is proposed. We study the symmetries of the corresponding heat kernel , which generalizes the bosonic one in a natural way. We used these symmetries to obtain, in the asymptotic limit,…

We use a multiresolution analysis based on a wavelet transform to upscale two-dimensional heterogeneous permeability fields. Results are compared with conventional averaging upscaling schemes using arithmetic, geometric and harmonic averaging. It is found that the wavelet analysis is able to…

Tsamparlis et al. [3] have developed a systematic method for computing of the conformal algebra of 1+3 space-times. The proper CKV's are found in terms of gradient CKVs of the 3-space. In this paper we apply Tsamparlis' results to the…

We introduce a realization of the algebra of diffeomorfisms in terms of the fields of a non-abelian Born-Infeld theory (NBI), which generalizes the abelian case. We argue that the non-abelian Born Infeld action which describes the interaction of D-branes in…

The classical two-dimensional problem of non-interacting electrons scattered by a static impurity potential in the presence of a magnetic field is investigated both analytically and numerically. A strong negative magnetoresistance is found, due to freely circling electrons, which are not…

Porous glasses can be synthesised by different methods: in the conventional ways such as foaming (foamed glasses) or phase separation and leaching process leading to the Vycor glass, and also by the sol-gel method (sintered xerogel and aerogel), or by…

The proposed method to count and differentiate nuclear tracks in Solid State Detectors is based on digital simulation and analysis of the Fraunhofer diffraction pattern, formed when coherent light passes through tracks in an etched detector. Analytical and numerical models…
