Pseudovorticity of 2+1D optical solitons
Ludovica Falsi, Giuseppe Agostino, Alberto Villois +6
In the hydrodynamic representation of a quantum fluid or optical field, vorticity vanishes wherever the phase is well defined, and is instead localized at phase singularities, or q…
Topological protection breakdown: a route to frustrated ferroelectricity
Ludovica Falsi, Pablo Villegas, Tommaso Gili +2
Phases manifesting topological patterns in functional systems, like ferroelectric and ferromagnetic vortex superlattices, can manifest intricate and apparently ungovernable behavio…
Evidence of 1+1D photorefractive stripe solitons deep in the Kerr limit
Ludovica Falsi, Alberto Villois, Francesco Coppini +3
The Kerr nonlinearity allows for exact analytic soliton solutions in 1+1D. While nothing excludes that these solitons form in naturally-occurring real-world 3D settings as solitary…
Evidence of hyperdimensional topological defects in a ferroelectric supercrystal phase-transition
Feifei Xin, Fabrizio Di Mei, Ludovica Falsi +5
We perform real-time stereoscopic wide-area imaging of a ferroelectric phase-transition in KTN:Li. Spontaneous polarization is observed to form a thermally hysteretic 3D lattice of…
Constraint-free wavelength conversion supported by giant optical refraction in a 3D perovskite supercrystal
Ludovica Falsi, Luca Tartara, Fabrizio Di Mei +8
Nonlinear response in a material increases with its index of refraction as . Commonly, 1 so that diffraction, dispersion, and chromatic walk-off limit nonlinear scatt…
Topological Control of Extreme Waves
Giulia Marcucci, Davide Pierangeli, Aharon J. Agranat +3
From optics to hydrodynamics, shock and rogue waves are widespread. Although they appear as distinct phenomena, new theories state that transitions between extreme waves are allowe…
