The Maghrebides are part of the peri-Mediterranean Alpine orogen. They expose in their inner zone inliers of high-grade crystalline rocks surrounded b...

The Green's function for a Klein-Gordon particle subjected to vector plus scalar Hulthen-type potentials is calculated in the path integral approach....

A simple tight-binding sp3s* model, which incorporates compositional disorder as an effective potential, is used for the calculations of the electroni...

The gas amplification properties have been investigated in four types of helium-isobutane gas mixtures consisting of 0.95, 2, 4 and 10% admixture of i...

We propose here a new model for the many-body problem that can be solved exactly through the diagonalization of its Hamiltonian. This model, which is...
