Three-dimensional optical vortices in nonlinear Bessel waveguides
Carlos F. Sánchez, Humberto Michinel, Boris Malomed +2
We explore the formation, stability, and propagation dynamics of light bullets carrying orbital angular momentum (vorticity) in Bessel-structured nonlinear graded-index waveguides.…
Guided vortex bullets
Carlos F. Sánchez, Ángel Paredes, Humberto Michinel +2
By means of the variational method and numerical simulations, we demonstrate the existence of stable 3D nonlinear modes, viz. vortex ``bullets'', in the form of pulsed beams carryi…
On the fate of travelling waves at the boundary of quantum droplets
Angel Paredes, Jose Guerra-Carmenate, Humberto Michinel
We analyze quantum droplets formed in a two-dimensional symmetric mixture of Bose-Einstein condensed atoms. For sufficiently large atom numbers, these droplets exhibit a flat-top d…
Traveling Bubbles and Vortex Pairs within Symmetric 2D Quantum Droplets
Angel Paredes, Jose Guerra-Carmenate, Jose R. Salgueiro +2
We disclose a class of stable nonlinear traveling waves moving at specific constant velocities within symmetric two-dimensional quantum droplets. We present a comprehensive analysi…
Photonic Nambu-Goldstone bosons
Miguel Ángel García-March, Ángel Paredes, Mario Zacarés +2
We study numerically the spatial dynamics of light in periodic square lattices in the presence of a Kerr term, emphasizing the peculiarities stemming from the nonlinearity. We find…
Coherent emission of atomic soliton pairs by Feshbach-resonance tuning
Humberto Michinel, Ángel Paredes, María M. Valado +1
We present two simple designs of matter-wave beam splitters in a trapped Bose-Einstein Condensate (BEC). In our scheme, identical pairs of atomic solitons are produced by an adequa…
