Journal ArticleDOI
Azimuthal vortex clusters in Bose-Einstein condensates
TL;DR: In this paper, the authors describe topologically nontrivial stationary states with azimuthal modulation of density in a repulsive Bose-Einstein condensate (BEC) confined in a harmonic trap.
Journal ArticleDOI
Nanoradar based on nonlinear dimer nanoantenna
TL;DR: In this article, the authors introduce the concept of a nanoradar based on the operation of a nonlinear plasmonic nanoantenna, which demonstrates a wide scanning sector, low operation threshold and ultrafast time response being potentially useful for many applications in nanophotonics circuitry.
Proceedings ArticleDOI
Nonlinear Optics of Metamaterials
TL;DR: In this article, the authors review theoretical and experimental results in different types of microwave metamaterials and backward-wave structures, including nonlinear transmission lines, two-dimensional cut-wire structures, and nonlinear split-ring resonator metammaterials.
Proceedings ArticleDOI
Partially incoherent optical vortices in self-focusing nonlinear media
TL;DR: It is predicted theoretically and experimentally stable propagation of spatially localized single- and double-charge optical vortices created in a self-focusing nonlinear medium by self-trapping of partially incoherent light carrying a phase dislocation.
Journal ArticleDOI
Nonlinear nanoantenna with self-tunable scattering pattern
TL;DR: In this paper, a nonlinear plasmonic nano-antenna with self-tunable scattering pattern (indicatrix) is proposed, where the onset of modulational instability in a nanoantenna consisting of two identical nonlinear metallic nanoparticles results in dynamic energy exchange between the eigenmodes of the nanodimer.
