We propose a scheme for stabilizing spatiotemporal solitons (STSs) in media with cubic self-focusing nonlinearity and "dispersion management," i.e., a layered structure inducing periodicallyâ€¦ (More)

We investigate the stability properties of breather solitons in a three-dimensional Bose-Einstein condensate with Feshbach resonance management of the scattering length and confined only by aâ€¦ (More)

We treat the behavior of Bose-Einstein condensates in double square well potentials of both equal and different depths. For even depth, symmetry preserving solutions to the relevant nonlinearâ€¦ (More)

Both symmetric and symmetry breaking analytic solutions to the one-dimensional nonlinear SchrÃ¶dinger equation with a double square well potential are known, but not straightforward to obtainâ€¦ (More)

We investigated the stability properties of breather soliton trains in a three-dimensional Boseâ€“Einstein condensate (BEC) with Feshbach-resonance management of the scattering length. This is done soâ€¦ (More)

Variational methods have become a widely used tool in the search for solitary waves in nonlinear systems. If a system exhibits fast oscillations in one of the degrees of freedom, its wavefunction canâ€¦ (More)

When looking for solitons in nonlinear systems, it is often useful to have a simplifying tool. One such tool is the variational method. On the other hand, in the presence of fast oscillations, theâ€¦ (More)

In two preceding papers (Infeld and Senatorski 2003 J. Phys.: Condens. Matter 15 5865, Senatorski and Infeld 2004 J. Phys.: Condens. Matter 16 6589) the authors confirmed Feynman's hypothesis on howâ€¦ (More)
