Dark excitons are exotic light-matter states found in atomically thin semiconductors. They usually remain invisible because ...

A new method for measuring three different properties of light, at the same time, has been developed using an ...

Researchers have now achieved high-Q photonic flatbands that span the entire k-space of nonlocal metasurfaces and can be selectively tailored for linearly polarized or circularly polarized light, ...

HOUSTON – (June 17, 2025) – Vacuum is often thought of as empty, but in fact it is teeming with fleeting energy fluctuations — virtual photons popping in and out of existence that can interact with ...

Ultrathin structures that can bend, focus, or filter light, metasurfaces are reshaping how scientists think about optics. These engineered materials offer precise control over lights behavior, but ...
