TENURED! Really excited and honored to get to spend many more years on this beautiful campus, with some of the best students and scholars in the world! @Cornell 1/4
We hope that this Roadmap, bringing together insights from different corners of this field, serves as a valuable guide to the current landscape of nonlocality in photonic materials and metamaterials and will inspire further innovation in expanding its frontier! @CornellEng
Just published in Optical Materials Express: "Nonlocality in photonic materials and metamaterials: Roadmap". https://t.co/FGIf4Su1qw This is the first-ever Roadmap published in OMEX, a great initiative launched by Andrea Alù in his role as Editor-in-Chief. Thank you @andrea_alu !
Check out the first OMEX Roadmap, timely focused on nonlocalities in optical materials. Thanks to @FMResearchGroup and Asger Mortensen for leading the effort and to all the authors. Looking forward to more Roadmaps to come.

A $100 million philanthropic commitment, the largest in @CornellEng's history, from David A. Duffield ’62, MBA ’64, will significantly expand the college’s existing Duffield Hall, creating a new state-of-the-art home for the School of Electrical and Computer Engineering and critical new lab space for strategic research priorities.

The paper is part of a Feature Issue on Nonlinear Nanophotonics, edited by Maxim Shcherbakov,
Mengjie Yu, Gregory Moille, Sebastian Schultz, Yuri Kivshar, and Robert Boyd.
New paper published in Optical Materials Express, with Theodoros Koutserimpas @tkoutserimpas, postdoc @CornellECE. Great collaboration with Hao Li and Prof. @owendmiller@Yale, as always! The paper was selected as an "Editor's Pick". https://t.co/Des8Y40yD4
One of the main results is a new set of sum rules that the transition dipole moments must satisfy. We discuss the implications of these results and the challenge of identifying fundamental limits to nonlinear optical responses. Related to this, see also https://t.co/Dk7OdULH7A
News & Views article by editor David Pile about our collaborative work on "diffractive robotics" led by the groups of Itai Cohen and Paul McEuen @Cornell.

Nice combo in this issue of @NaturePhotonics: A News & Views article we wrote, with @CornellECE PhD graduate @zekihayran ["A resonant tone for photonic time crystals"] + A News & Views article written about our work by Dr. @DavidPile1 ["Magnetically driven photonic ‘microbots’"]!
In this N&V, we discussed the emerging topic of "photonic time crystals" and the nice work by the groups of @CRockstuhl & V. Asadchy on using resonances to expand momentum bandgaps.

In this brief Opinion article, with PhD Student Matteo Ciabattoni @CornellECE & Prof. Dimitrios Sounas @WayneStateEng, we discuss time-periodic (Floquet) systems in classical wave physics and engineering. Published this week in Optical Materials Express.

More broadly, we think this work & many other contributions by several groups show that we are just scratching the surface on the potential of temporal degrees of freedom to go beyond the fundamental limits of LTI systems. E.g., https://t.co/d58fZaJgC3 & https://t.co/62xom3kbkh
Our findings show that a periodically modulated time-varying system can exceed relevant absorption limits, such as those based on the Rozanov bound for LTI absorbers, by increasing the energy dissipated on a lossy element through interference between harmonics.
We show that this is possible over broad continuous bandwidths, with a structure thinner than the spatial width of the incident pulse, and without energy exchange with the modulator. We also discuss outstanding challenges, practical implications, and possible future directions.
Our paper on the experimental demonstration of enhanced broadband absorption of electromagnetic waves in time-varying systems was published in @ScienceAdvances, w/ @CornellECE PhD student Matteo Ciabattoni and recent graduate Dr. Zeki Hayran @zekihayran https://t.co/CXEXCu7wux
"Scattering Bodies as Matrix-Valued Oscillators" - Our work led by @owendmiller on a new theoretical framework for scattering theory was highlighted in Optics & Photonics News' #Opticsin2024. @CornellECE
See the original @NatureComms paper here: https://t.co/Lb2sBLyrhc
Highlighted in OPN's #OpticsIn2024:
A new framework for scattering theory that offers guidance on design questions, and a new representation via Drude–Lorentz oscillators with matrix-valued (spatially nonlocal) coefficients.
