Can Light Cross a Singularity? Exact Solutions from Analogue Gravity
Juan Manuel Paez, Franco Fiorini, Santiago M. Hernández
Using a simple spacetime hosting a strong curvature naked singularity, we employ an analogue gravity model to study electromagnetic fields in this background. We find exact solutio…

Shedding Light on Naked Singularities
Franco Fiorini, Santiago Hernandez, Juan Manuel Paez
Electromagnetic waves propagating in the background provided by a spacetime hosting a strong curvature, naked singularity, are fully studied. The analysis is performed not only in…

Soliton generation through temporal reflection in media with a frequency-dependent nonlinearity
Lucas N. Gutierrez, Pablo I. Fierens, Diego F. Grosz +1
We demonstrate that the temporal reflection of a weak dispersive pulse on a soliton in media with a frequency-dependent nonlinearity leads to the generation of new solitons, whose…
