Experimental Demonstration of 7-Dimensional N-Vector Model with Dimensional Inflation and Annealing
Daniele Veraldi, Marcello Calvanese Strinati, Paolo Charlesworth +4
We report the first experimental realization of a physical system described by a high-dimensional Hamiltonian comprising up to seven dimensions. Our setup is based on a holographic…
Precision Hamiltonian Encoding in Full-Aperture Spatial Photonic Ising Machines
P. S. Karavelas, D. Karanikolopoulos, L. Mouchliadis +11
Spatial photonic Ising machines (SPIMs) offer compact, room-temperature hardware with inherently parallel, energy-efficient, single-shot optical evaluation of the Ising Hamiltonian…
Phase Retrieval via Gain-Based Photonic XY-Hamiltonian Optimization
Richard Zhipeng Wang, Guangyao Li, Silvia Gentilini +3
Phase-retrieval from coded diffraction patterns (CDP) is important to X-ray crystallography, diffraction tomography and astronomical imaging, yet remains a hard, non-convex inverse…
Fully Programmable Spatial Photonic Ising Machine by Focal Plane Division
Daniele Veraldi, Davide Pierangeli, Silvia Gentilini +10
Ising machines are an emerging class of hardware that promises ultrafast and energy-efficient solutions to NP-hard combinatorial optimization problems. Spatial photonic Ising machi…
Coexistence of local and nonlocal shock waves in nanomaterials
Ilaria Gianani, Silvia Gentilini, Iole Venditti +3
High-performing nanomaterials are paramount for advanced photonic technologies, like sensing, lasing, imaging, data storage, processing, and medical and biological applications. Me…
Heterogeneous Random Laser with Switching Activity Visualized by Replica Symmetry Breaking Maps
Loredana M. Massaro, Silvia Gentilini, Alberto Portone +4
In the past decade, complex networks of light emitters are proposed as novel platforms for photonic circuits and lab-on-chip active devices. Lasing networks made by connected multi…
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…
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…
Relativistic regimes for dispersive shock-waves in non-paraxial nonlinear optics
Silvia Gentilini, Eugenio DelRe, Claudio Conti
We investigate the effect of non-paraxiality in the dynamics of dispersive shock waves in the defocusing nonlinear Schroedinger equation. We show that the problem can be described…
Optomechanics of random media
Silvia Gentilini, Claudio Conti
Using light to control the movement of nano-structured objects is a great challenge. This challenge involves fields like optical tweezing, Casimir forces, integrated optics, bio-ph…
Shock waves in disordered media
N. Ghofraniha, S. Gentilini, V. Folli +2
We experimentally investigate the interplay between spatial shock waves and the degree of disorder during nonlinear optical propagation in a thermal defocusing medium. We character…
Signatures of the Anderson localization excited by an optical frequency comb
Claudio Conti, Andrea Fratalocchi, Silvia Gentilini
We investigate Anderson localization of light as occurring in ultra-short excitations. A theory based on time dependent coupled-mode equations predicts universal features in the sp…
Ultrashort pulse propagation and the Anderson localization
Silvia Gentilini, Andrea Fratalocchi, Luca Angelani +2
We investigate the dynamics of a 10 fs light pulse propagating in a random medium by the direct solution of the 3D Maxwell equations. Our approach employs molecular dynamics to gen…
