Virtual states of light non-Borromean halo nuclei
A. Delfino, T. Frederico, M. S. Hussein +1
It is shown that the three-body non-Borromean halo nuclei like ^{12}Be, ^{18}C, ^{20}C have p-wave virtual states with energy of about 1.6 times the corresponding neutron-core bind…
Atomic Bose-Einstein Condensation with Three-Body Interactions and Collective Excitations
A. Gammal, T. Frederico, Lauro Tomio +1
The stability of a Bose-Einstein condensed state of trapped ultra-cold atoms is investigated under the assumption of an attractive two-body and a repulsive three-body interaction.…
Liquid-Gas phase transition in Bose-Einstein Condensates with time evolution
A. Gammal, T. Frederico, Lauro Tomio +1
We study the effects of a repulsive three-body interaction on a system of trapped ultra-cold atoms in Bose-Einstein condensed state. The stationary solutions of the corresponding $…
On high behavior of the pion form factor for transitions and within the nonlocal quark-pion model
I. V. Anikin, A. E. Dorokhov, Lauro Tomio
The behavior of the transition pion form factor for processes γ^*γ-> π^0 and γ^* γ^* -> π^0 at large values of space-like photon momenta is estimated within the nonlocal covariant…
Non-linear Regge spectrum fits to experimentally up-dated meson states
Jishnu Dey, Mira Dey, P. Leal Ferreira +1
The exciting feature of recent times is the inflow of new experimental data. Fits to the $π, \r$ and f meson resonances found by the VES collaboration, along with those of the PDG…
Improved numerical approach for time-independent Gross-Pitaevskii nonlinear Schroedinger equation
A. Gammal, T. Frederico, L. Tomio
In the present work, we improve a numerical method, developed to solve the Gross-Pitaevkii nonlinear Schroedinger equation. A particular scaling is used in the equation, which perm…
