The thermodynamic properties of the mixed spin-3/2 and spin-1/2 Heisenberg model are examined within the Oguchi approximation in the presence of a random crystal-field (RCF). The RCF is either introduced with probability p or turned off with probabil [...]

The ease of prescribing radiological examinations has prompted an expansion in radiological pro- cedures and, consequently, an increase of occupational dose to medical imaging workers. However, little is known about radiation exposure in the workpl [...]
In this paper, we study coherent states for a quantum Pauli model through supersym- metric quantum mechanics (SUSYQM) method. From the point of view of canonical quantization, the construction of these coherent states is based on the very important [...]

In this paper, we use some well-known tech- niques of Supersymmetric Quantum Mechanics (SUSYQM) namely the factorization method and shape invariance, to generate new analytically solvable potentials from some interacting fermionic models in nonre [...]

It is well known that the representations over an arbitrary configuration space related to a physical system of the Heisenberg algebra allow to distinguish the simply and non simply-connected manifolds [arXiv:quant-ph/9908.014, arXiv:hep-th/0608.02 [...]

This paper deals with an extension of a previous work [Gravitation & Cosmology, Vol. 4, 1998, pp. 107-113] to exact spherical symmetric solutions to the spinor field equations with nonlinear terms which are arbitrary functions, taking into account th [...]

Dans ce travail nous sommes intéressés à l’étude d’un model fermionique dans un espace noncommutative pourvue d’une métrique de type corde cosmique. La métrique étant non triviale il faut de nouvelles méthodes pour comprendre comment traiter de façon [...]
Un opérateur de récursion pour un écoulement géodésique, dans un espace non commutatif (NC) doté d'une métrique de Minkowski, est construit et discuté dans ce travail. Une fonction Hamiltonienne Hnc décrivant la dynamique d’une particule libre dans [...]
Dans ce travail nous étudions les principes du maximum et de l'antimaximum pour le p-Laplacien soumis aux conditions aux limites de Steklov et en présence de fonctions poids pouvant changer de signe. Noud donnons la caractérisation de l'intervalle de [...]
