Splay-induced charging of ferroelectric droplets in highly non-uniform electric fields
Lorenzo Fiorentini, Elia Rocchetti, Raouf Barboza +2
Ferroelectric sessile droplets on a superhydrophobic surface can be put into motion by highly non-uniform electric fields, in a direction that depends on the field sign. This indic…
Programmable non-Hermitian photonic quantum walks via dichroic metasurfaces
Paola Savarese, Sarvesh Bansal, Maria Gorizia Ammendola +6
The evolution of a closed quantum system is described by a unitary operator generated by a Hermitian Hamiltonian. However, when certain degrees of freedom are coupled to an environ…
Electrically tunable liquid-crystal metasurfaces with patterned birefringence and dichroism
Paola Savarese, Sarvesh Bansal, Maria Gorizia Ammendola +7
Light propagation through artificially patterned anisotropic materials, such as dielectric metasurfaces, enables precise control of the spatio-vectorial properties of optical field…
Optical Control Of Mass Ejection From Ferroelectric Liquid Droplets: A Possible Tool For The Actuation Of Complex Fluids
Stefano Marni, Raouf Barboza, Annamaria Zaltron +1
We report on the optical control of the recently observed electromechanical instability of ferroelectric liquid droplets exposed to the photovoltaic field of a lithium niobate ferr…
Walk ferroelectric liquid droplets with light
Stefano Marni, Giovanni Nava, Raouf Barboza +2
We show that the motion of ferroelectric liquid sessile droplets deposited on a ferroelectric lithium niobate substrate can be controlled by a light beam of moderate intensity irra…
Explosive electrostatic instability of ferroelectric liquid droplets on ferroelectric solid surfaces
Raouf Barboza, Stefano Marni, Fabrizio Ciciulla +7
We investigated the electrostatic behavior of ferroelectric liquid droplets exposed to the pyroelectric field of a lithium niobate ferroelectric crystal substrate. The ferroelectri…
Quantum walks of two correlated photons in a 2D synthetic lattice

Quantum walks represent paradigmatic quantum evolutions, enabling powerful applications in the context of topological physics and quantum computation. They have been implemented in…
Ultra-sensitive measurement of transverse displacements with structured light
Raouf Barboza, Amin Babazadeh, Lorenzo Marrucci +3
Accurately measuring mechanical displacements is essential for a vast portion of current technologies. Several optical techniques accomplish this task, allowing for non-contact sen…
Bloch-Landau-Zener dynamics induced by a synthetic field in a photonic quantum walk
Alessio D'Errico, Raouf Barboza, Rebeca Tudor +4
Quantum walks are processes that model dynamics in coherent systems. Their experimental implementations proved key to unveil novel phenomena in Floquet topological insulators. Here…
Bulk detection of time-dependent topological transitions in quenched chiral models
Alessio D'Errico, Francesco Di Colandrea, Raouf Barboza +5
The topology of one-dimensional chiral systems is captured by the winding number of the Hamiltonian eigenstates. Here we show that this invariant can be read-out by measuring the m…
Temporal dynamics of light-written waveguides in unbiased liquid crystals
Alessandro Alberucci, Raouf Barboza, Chandroth P. Jisha +1
The control of light by light is one of the main aims in modern photonics. In this context, a fundamental cornerstone is the realization of light-written waveguides in real time, r…
Two-dimensional topological quantum walks in the momentum space of structured light
Alessio D'Errico, Filippo Cardano, Maria Maffei +7
Quantum walks are powerful tools for quantum applications and for designing topological systems. Although they are simulated in a variety of platforms, genuine two-dimensional real…
Berry phase of light Bragg-reflected by chiral liquid crystal media
Raouf Barboza, Umberto Bortolozzo, Stefania Residori +1
Berry phase is revealed for circularly polarized light when it is Bragg-reflected by a chiral liquid crystal medium of the same handedness. By using a chiral nematic layer we demon…
