Persistent entanglement due to helicity conservation in excitable media
José L. Trueba, Manuel Arrayás
This work addresses the topic of knotted stable structures in excitable media. These structures appear in a wide variety of situations, such as cardiac fibrillation, chemical react…

Power laws and self-similar behavior in negative ionization fronts
Manuel Arrayás, Marco A. Fontelos, José L. Trueba
We study anode-directed ionization fronts in curved geometries. When the magnetic effects can be neglected, an electric shielding factor determines the behavior of the electric fie…

On negative streamers: a deterministic approach
Manuel Arrayás
In dielectric breakdown, the phenomena of streamers formation and spontaneous branching is commonly observed. A deterministic negative streamer model is reviewed in this article. W…
