Polaritons enable tunable and efficient molecular charge transfer across broader spectrum of light

Polaritons are quasiparticles emerging from strong interactions between light particles (i.e., photons) and matter excitations (e.g., excitons). Over the past few years, researchers have found that these quasiparticles can ...

JWST reveals 3I/ATLAS's coma is largely carbon dioxide

All (or at least most) astronomical eyes are on 3I/ATLAS, our most recent interstellar visitor that was discovered in early July. Given its relatively short observational window in our solar system, and especially its impending ...
