Using the bound state version of the topological soliton model for the baryons we show that the existence of a bound (or quasi-bound) D-soliton state leads to the possibility of having hidden charm pentaquarks with quantum ...

Abstract: We study the collisional dynamics of multiple dark solitons in a Bose–Einstein condensate confined by a toroidal trap. We assume a tight enough confinement in the radial direction to prevent possible dissipative ...

This paper is concerned with Chern-Ricci flow evolution of left-invariant hermitian structures on Lie groups. We study the behavior of a solution, as t is approaching the first time singularity, by rescaling in order to ...

In this work we apply a nonperturbative approach to analyze soliton bifurcation ill the presence of surface tension, which is a reformulation of standard methods based on the reversibility properties of the system. The ...

Los fenómenos asociados a las ondas se pueden separar en dos tipos, según el tipo de medio en el que estas se propagan. Primero están las ondas planas, las cuales se propagan en medios lineales disipativos o no disipativos. ...

In this note we investigate the influence of structural nonlinearity of a simple cantilever beam impacting system on its dynamic responses close to grazing incidence by a means of numerical simulation. To obtain a clear ...

We study the existence of homoclic solutions for reversible Hamiltonian systems taking the family of differential equations u(iv) + au - u +f(u, b) = 0 as a model, where fis an analytic function and a, b real parameters. ...
