Modulational instability windows in the nonlinear Schrödinger equation involving higher-order Kerr responses
David Novoa, Daniele Tommasini, José A. Nóvoa-López
We introduce a complete analytical and numerical study of the modulational instability process in a system governed by a canonical nonlinear Schrödinger equation involving local, a…
Dynamical generation of interwoven soliton trains by nonlinear emission in binary Bose-Einstein condensates
V. A. Brazhnyi, David Novoa, Chandroth P. Jisha
We propose a method for the generation of trains of alternating bright solitons in two-component Bose-Einstein condensates, using controlled emission of nonlinear matter-waves in t…
Spontaneous symmetry breaking in synchronously pumped fiber ring cavities
Michael J. Schmidberger, David Novoa, Fabio Biancalana +2
We introduce a new equation that describes the spatio-temporal evolution of arbitrary pulses propagating in a fiber-ring cavity. This model is a significant extension of the tradit…
Ultrasolitons: multistability and subcritical power threshold from higher-order Kerr terms
David Novoa, Daniele Tommasini, Humberto Michinel
We show that an optical system involving competing higher-order Kerr nonlinearities can support the existence of ultrasolitons, namely extremely localized modes that only appear ab…
Coherent atomic soliton molecules for matter-wave switching
Chenyun Yin, Natalia G. Berloff, Víctor M. Pérez-García +3
We discuss the dynamics of interacting dark-bright two-dimensional vector solitons in multicomponent immiscible bulk Bose-Einstein condensates. We describe matter-wave molecules wi…
Fermionic light in common optical media
David Novoa, Humberto Michinel, Daniele Tommasini
Recent experiments have proved that the response to short laser pulses of common optical media, such as air or Oxygen, can be described by focusing Kerr and higher order nonlineari…
Filamentation processes and dynamical excitation of light condensates in optical media with competing nonlinearities
David Novoa, Humberto Michinel, Daniele Tommasini +1
We analyze both theoretically and by means of numerical simulations the phenomena of filamentation and dynamical formation of self-guided nonlinear waves in media featuring competi…
Dripping, pressure and surface tension of self-trapped laser beams
David Novoa, Humberto Michinel, Daniele Tommasini
We show that a laser beam which propagates through an optical medium with Kerr (focusing) and higher order (defocusing) nonlinearities displays pressure and surface-tension propert…
Supersolitons: Solitonic excitations in atomic soliton chains
David Novoa, Boris A. Malomed, Humberto Michinel +1
We show that, by appropriately tuning physically relevant interactions in two-component nonlinear Schrodinger equations, it is possible to achieve a regime with particle-like solit…
Non-quantum liquefaction of coherent gases
David Novoa, Humberto Michinel, Daniele Tommasini +1
We show that a gas-to-liquid phase transition at zero temperature may occur in a coherent gas of bosons in the presence of competing nonlinear effects. This situation can take plac…
