Fast and length-independent transport time supported by topological edge states in finite-size Su-Schrieffer-Heeger chains
Yu-Han Chang, Nadia Daniela Rivera Torres, Santiago Figueroa Manrique +9
In order to transport information with topological protection, we explore experimentally the fast transport time using edge states in one-dimensional Su-Schrieffer-Heeger (SSH) cha…
Beam deflection and negative drag in a moving nonlinear medium
Ryan Hogan, Akbar Safari, Giulia Marcucci +2
Light propagating in a moving medium with refractive index other than unity is subject to light drag. While the light drag effect due to the linear refractive index is often neglig…
Anomalous Optical Drag
Chitram Banerjee, Yakov Solomons, A. Nicholas Black +5
A moving dielectric medium can displace the optical path of light passing through it, a phenomenon known as the Fresnel-Fizeau optical drag effect. The resulting displacement is pr…
Adiabatic evolution on a spatial-photonic Ising machine
D. Pierangeli, G. Marcucci, C. Conti
Combinatorial optimization problems are crucial for widespread applications but remain difficult to solve on a large scale with conventional hardware. Novel optical platforms, know…
Noise-enhanced spatial-photonic Ising machine
Davide Pierangeli, Giulia Marcucci, Daniel Brunner +1
Ising machines are novel computing devices for the energy minimization of Ising models. These combinatorial optimization problems are of paramount importance for science and techno…
Multidimensional topological strings by curved potentials: Simultaneous realization of mobility edge and topological protection
Chun-Yan Lin, Giulia Marcucci, Gang Wang +3
By considering a cigar-shaped trapping potential elongated in a proper curvilinear coordinate, we discover a new form of wave localization which arises from the interplay of geomet…
Theory of neuromorphic computing by waves: machine learning by rogue waves, dispersive shocks, and solitons
Giulia Marcucci, Davide Pierangeli, Claudio Conti
We study artificial neural networks with nonlinear waves as a computing reservoir. We discuss universality and the conditions to learn a dataset in terms of output channels and non…
Anisotropic Optical Shock Waves in Isotropic Media with Giant Nonlocal Nonlinearity
Giulia Marcucci, Phillip Cala, Weining Man +3
Dispersive shock waves in thermal optical media belong to the third-order nonlinear phenomena, whose intrinsic irreversibility is described by time asymmetric quantum mechanics. Re…
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…
Optical Spatial Shock Waves in Nonlocal Nonlinear Media
Giulia Marcucci, Davide Pierangeli, Silvia Gentilini +3
Dispersive shock waves are fascinating phenomena occurring when nonlinearity overwhelms linear effects, such as dispersion and diffraction. Many features of shock waves are still u…
Large-scale photonic Ising machine by spatial light modulation
D. Pierangeli, G. Marcucci, C. Conti
Quantum and classical physics can be used for mathematical computations that are hard to tackle by conventional electronics. Very recently, optical Ising machines have been demonst…
Quantum-gravity-slingshot: orbital precession due to the modified uncertainty principle, from analogs to tests of Planckian physics with quantum fluids
Giulia Marcucci, Claudio Conti
Modified uncertainty principle and non-commutative variables may phenomenologically account for quantum gravity effects, independently of the considered theory of quantum gravity.…
Machine Learning Inverse Problem for Topological Photonics
Laura Pilozzi, Francis A. Farrelly, Giulia Marcucci +1
Topological concepts open many new horizons for photonic devices, from integrated optics to lasers. The complexity of large scale topological devices asks for an effective solution…
Nonlinear Gamow vectors, shock waves and irreversibility in optically nonlocal media
Silvia Gentilini, Maria Chiara Braidotti, Giulia Marcucci +2
Dispersive shock waves dominate wave-breaking phenomena in Hamiltonian systems. In the absence of loss, these highly irregular and disordered waves are potentially reversible. Howe…
