Reorientational solitons in nematic liquid crystals with modulated alignment

Autor: Sala, Filip A., Smyth, Noel F., Laudyn, Urszula A., Karpierz, Mirosław A., Minzoni, Antonmaria A., Assanto, Gaetano

In uniaxial soft matter with a reorientational nonlinearity, such as nematic liquid crystals, a light beam in the extraordinary polarization walks off its wavevector due to birefringence, while it undergoes self-focusing via an increase in refractive

A chemotactic model for interaction of antagonistic microflora colonies: front asymptotics and numerical simulations

Autor: Malaga, Carlos, Minzoni, Antonmaria, Plaza, Ramon G., Simeoni, Chiara

This paper studies a two-dimensional chemotactic model for two species in which one of them produces a chemo-repellent for the other. It is shown asymptotically and numerically how the chemical inhibits the invasion of a moving front for the second s

Report

Vector vortex solitons in nematic liquid crystals

Autor: Xu, Zhiyong, Smyth, Noel F., Minzoni, Antonmaria A., Kivshar, Yuri S.

Publikováno v: Optics Letters 34, 1414 (2009)

We analyze the existence and stability of two-component vector solitons in nematic liquid crystals for which one of the components carries angular momentum and describes a vortex beam. We demonstrate that the nonlocal, nonlinear response can dramatic
