Nonlinear Spectral Computing
Ludovica Falsi, Francesco Coppini, Claudio Conti
Many machine learning algorithms rely on the Fourier transform, which is also the inner core of many analog computing devices and, specifically, of optical computing. The square of…
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…
