Competing Auger-Like and Intraband Excitations Drive Anomalous Modulations in Indium Tin Oxide
Anthony C Harwood, Sean Z J Lim, T V Raziman +7
Transparent conducting oxides near their epsilon-near-zero frequency exhibit near-unity ultrafast modulations of the refractive index which have enabled the field of time-varying m…

Optical coherent perfect absorption and amplification in a time-varying medium
Emanuele Galiffi, Anthony C. Harwood, Stefano Vezzoli +3
Time-invariant photonic structures amplify or absorb light based on their intrinsic material gain or loss. The coherent interference of multiple beams in space, e.g., in a resonato…

Space-Time Optical Diffraction from Synthetic Motion
A. C. Harwood, S. Vezzoli, T. V. Raziman +7
The interaction of light with objects and media moving at relativistic and superluminal speeds enables unconventional phenomena such as Fresnel drag, Hawking radiation, and light a…
