Dynamics of bright matter-wave solitons in inhomogeneous cigar-type Bose-Einstein condensate
F. Kh. Abdullaev, A. Gammal, L. Tomio
We discuss the possible observation of a new type of standing nonlinear atomic matter wave in the condensate: the nonlinear impurity mode. It is investigated dynamical effects of a…
Scaling limit of virtual states of triatomic systems
M. T. Yamashita, T. Frederico, A. Delfino +1
For a system with three identical atoms, the dependence of the wave virtual state energy on the weakly bound dimer and trimer binding energies is calculated in a form of a univ…
Critical numbers of attractive Bose-condensed atoms in asymmetric traps
A. Gammal, L. Tomio, T. Frederico
The recent Bose-Einstein condensation of ultracold atoms with attractive interactions led us to consider the novel possibility to probe the stability of its ground state in arbitra…
Effect of anharmonicities in the critical number of trapped condensed atoms with attractive two-body interaction
Victo S. Filho, Arnaldo Gammal, Lauro Tomio
We determine the quantitative effect, in the maximum number of particles and other static observables, due to small anharmonic terms added to the confining potential of an atomic c…
Light-front model of the kaon electromagnetic current
J. P. B. C. de Melo, Lauro Tomio, T. Frederico
The electromagnetic form factor is extracted from both components of the electromagnetic current: J(plus) and J(minus) with a pseudo-scalar coupling of the quarks to the kaon. In t…
Stability of the trapped nonconservative Gross-Pitaevskii equation with attractive two-body interaction
Victo S. Filho, T. Frederico, Arnaldo Gammal +1
The dynamics of a nonconservative Gross-Pitaevskii equation for trapped atomic systems with attractive two-body interaction is numerically investigated, considering wide variations…
