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.…
Exceptional light propagation via generalized bulk-edge correspondence
Heitor da Silva, Sergey K. Ivanov, Isaac Suárez +2
In topological photonics, the bulk-edge correspondence is conventionally imported by direct analogy with electronic systems, overlooking the fundamentally distinct spacetime symmet…
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…
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…
Spatial solitons in thermo-optical media from the nonlinear Schrodinger-Poisson equation and dark matter analogues
Alvaro Navarrete, Angel Paredes, Jose R. Salgueiro +1
We analyze theoretically the Schrodinger-Poisson equation in two transverse dimensions in the presence of a Kerr term. The model describes the nonlinear propagation of optical beam…
Mapped Chebyshev pseudospectral method to study multiple scale phenomena
Adrian Alexandrescu, Alfonso Bueno-Orovio, Jose R. Salgueiro +1
In the framework of mapped pseudospectral methods, we introduce a new polynomial-type mapping function in order to describe accurately the dynamics of systems developing almost sin…
