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…
Photoionization effects in streamer discharges
M. Arrayas, M. A. Fontelos, J. L. Trueba
In this paper we study the effects of photoionization processes on the propagation of both negative and positive streamer discharges. We show that negative fronts accelerate in the…
On the mechanism of branching in negative ionization fronts
M. Arrayas, M. A. Fontelos, J. L. Trueba
We explain a mechanism for branching of a planar negative front. Branching occurs as the result of a balance between the destabilizing effect of impact ionization and the stabilizi…
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…
Ionization fronts in negative corona discharges
Manuel Arrayas, Marco A. Fontelos, Jose L. Trueba
In this paper we use a hydrodynamic minimal streamer model to study negative corona discharge. By reformulating the model in terms of a quantity called shielding factor, we deduce…
