Professor Luca Dal Negro’s joint paper in Physical Review B was selected as an Editor’s Suggestion.
Professor Dal Negro and his collaborator Prof. Marco Ornigotti (Tampere University, Finland) have recently published a joint paper in Physical Review B that was selected as an “Editors’ Suggestion” (an honor conferred on the top 10% of all accepted papers). The designation recognizes their rigorous and comprehensive first theoretical analysis of quantum effects in nonlienear nanostructures at the single photon level (Phys. Rev. B, 112, 165433, 2025).
In particular, the authors demonstrate the enhanced nonlinear optical response of epsilon-near-zero (ENZ) nanostructures of indium-tin-oxide (ITO) materials at the single photon level using fully nonperturbative quantum theory of open systems. Closed-form analytical results obtained for spherical nanoparticles were numerically validated and extended to geometries that can be fabricated using state-of-the-art electron-beam lithography, establishing a rigorous benchmark for understanding quantum nonlinear effects in nonlinear nanostructures with realistic optical losses. Their results have been characterized by the reviewers as “important for quantum technology” and “a rigorous and timely study with clear novelty and potential impact in the field of quantum nanophotonics.”
Professor Luca Dal Negro earned his PhD at the University of Trento, Italy, in 2003. He is an Optica Fellow, and the recipient of several early career awards. His research interests include nanophotonics and metamaterials, nonlinear and quantum optics, laser physics, wave localization phenomena and diffractive optics for advanced imaging and multifunctional optical devices.
