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, Ãngel 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…
