Galilean Invariance in the Characterization of Light Drag in Moving Atomic Vapor
Edgar S. Arroyo-Rivera, Long D. Nguyen, Surendar Vijayakumar +2
Light experiences drag effects when it propagates through a moving medium. The study of light drag has provided foundational insights into light-matter interactions. While longitud…

Hybrid Deep Reconstruction for Vignetting-Free Upconversion Imaging through Scattering in ENZ Materials
Hao Zhang, Yang Xu, Wenwen Zhang +10
Optical imaging through turbid or heterogeneous environments (collectively referred to as complex media) is fundamentally challenged by scattering, which scrambles structured spati…

High-fidelity spatial information transfer through dynamic scattering media by an epsilon-near-zero time-gate
Yang Xu, Saumya Choudhary, Long D. Nguyen +7
Transparent conducting oxides (TCO) such as indium-tin-oxide (ITO) exhibit strong optical nonlinearity in the frequency range where their permittivities are near zero. We leverage…
