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…
