From localized spots to the formation of invaginated labyrinthine structures in a Swift-Hohenberg model

Bordeu, I.; Clerc Gavilán, Marcel; Lefever, R.; Tlidi, M. (Elsevier, 2015)

The stability of a circular localized spot with respect to azimuthal perturbations is studied in a prototype variational model, namely, a Swift-Hohenberg type equation. The conditions under which the circular shape of the ...

Localised labyrinthine patterns in ecosystems

Clerc Gavilán, Marcel Gabriel; Echeverría Alar, S.; Tlidi, M. (Nature Research, 2021)

Self-organisation is a ubiquitous phenomenon in ecosystems. These systems can experience transitions from a uniform cover towards the formation of vegetation patterns as a result of symmetry-breaking instability. They can ...

Localized plateau beam resulting from strong nonlocal coupling in a cavity filled by metamaterials and ...

Tlidi, M.; Fernández Oto, C.; Clerc Gavilán, Marcel; Escaff Dixon, Daniel; Kockaert, P. (American Physiological Society, 2015)

We investigate the formation of a localized plateau beam in the transverse section of a nonlinear optical ring cavity filled with a metamaterial and a nonlocal medium such as a nematic liquid crystal. We show that, far ...

Localized vegetation patterns, fairy circles, and localized patches in arid landscapes

Escaff, D.; Fernández Oto, C.; Clerc Gavilán, Marcel; Tlidi, M. (American Physical Society, 2015)

We investigate the formation of localized structures with varying widths in one- and two-dimensional systems. The mechanism of stabilization is attributed to strongly nonlocal coupling mediated by a Lorentzian type ...
