Dynamics of vortex-antivortex pairs and rarefaction pulses in liquid light
David Feijoo, Angel Paredes, Humberto Michinel
We present a numerical study of the cubic-quintic nonlinear Schrödinger equation in two transverse dimensions, relevant for the propagation of light in certain exotic media. A well…
Drag force in bimodal cubic-quintic nonlinear Schrödinger equation
David Feijoo, Ismael Ordóñez, Ángel Paredes +1
We consider a system of two cubic-quintic non-linear Schrödinger equations in two dimensions, coupled by repulsive cubic terms. We analyse situations in which a probe lump of one o…
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…
Outcoupling vector solitons from a Bose-Einstein condensate with time-dependent interatomic forces
David Feijoo, Ángel Paredes, Humberto Michinel
We discuss the possibility of emitting vector solitons from a two-component elongated BEC by manipulating in time the inter- or intra-species scattering lengths with Feshbach reson…
Coherent Cavitation in the Liquid of Light
Ángel Paredes, David Feijoo, Humberto Michinel
We study the cubic- (focusing-)quintic (defocusing) nonlinear Schrödinger equation in two transverse dimensions. We discuss a family of stationary traveling waves, including rarefa…
Two-dimensional solitons in conservative and parity-time-symmetric triple-core waveguides with cubic-quintic nonlinearity
David Feijoo, Dmitry A. Zezyulin, Vladimir V. Konotop
We analyze a system of three two-dimensional nonlinear Schrödinger equations coupled by linear terms and with the cubic-quintic (focusing-defocusing) nonlinearity. We consider two…
