When the Hall effect is included in the magnetohydrodynamics equations (Hall-MHD model) the wave propagation modes become coupled, but for propagation parallel to the ambient magnetic field the Alfvén mode decouples from ...

We examine a fractional version of the discrete nonlinear Schrodinger (dnls) equation, where the usual discrete laplacian is replaced by a fractional discrete laplacian. This leads to the replacement of the usual ...

In previous papers, the type-I intermittent phenomenon with continuous reinjection probability density (RPD) has been extensively studied. However, in this paper type-I intermittency considering discontinuous RPD function ...

We study the bulk and surface nonlinear modes of a modi ed one-dimensional discrete nonlinear Schrödinger (mDNLS) equation. A linear and a modulational stability analysis of the lowest- order modes is carried out. While ...

Estudiarnos la localización de un electrón o excitación en redes tight-bi.nd,ing debida a la interacción con fonones, usando el modelo cuántico de Holstein, o a efectos nolineales locales modelados con la ecuación de ...

We study a fractional version of the two-dimensional discrete nonlinear Schrodinger (DNLS) equation, where the usual discrete Laplacian is replaced by its fractional form that depends on a fractional exponent s that ...

We use the discrete nonlinear Schrödinger (DNLS) equation to show that nonlinear tight-binding lattices of different geometries and dimensionalities display a universal self-trapping behavior. First, we consider the problem ...
