High-harmonic generation in systems with chiral Bloch states: application to rhombohedral graphene
Jessica O. de Almeida, Wilton J. M. Kort-Kamp, Mathias S. Scheurer
Nonlinear light-matter interaction and, in particular, high-harmonic generation (HHG) are fundamentally interesting and frequently discussed as versatile probes of quantum material…
Polar enhancement of optical nonlinearities and domain-driven second harmonic contrast in bismuth telluro-halide van der Waals crystals
Kevin W. C. Kwock, Tenzin Norden, Thomas P. Darlington +11
The BiTeX family of polar van der Waals (vdW) semiconductors offers a unique platform for exploring the interplay between polar crystalline structure and nonlinear optical phenomen…
Near-field-driven Radiative Thermal Dynamics in Aperiodic Nanostructures
M. Prado, A. Manjavacas, F. A. Pinheiro +1
Harnessing structural correlations in near-field plasmonic and polaritonic systems hold untapped potential for controlling light-matter interactions at the nanoscale. By tuning the…
Meta-GPT: Decoding the Metasurface Genome with Generative Artificial Intelligence
David Dang, Stuart Love, Meena Salib +8
Advancing artificial intelligence for physical sciences requires representations that are both interpretable and compatible with the underlying laws of nature. We introduce METASTR…
Breakdown of the Kirchhoff's law of thermal radiation by a spatiotemporally modulated nonreciprocal metasurface
Anatoly Efimov, Chun-Chieh Chang, Simo Pajovic +5
Kirchhoff's law of thermal radiation, which dictates that the emissivity of a surface equals its absorptivity under thermal equilibrium, which dictates that the emissivity of a sur…
