Beyond Duality: How ‘Dark States’ Are Redefining The Nature Of Light

A foundational pillar of quantum mechanics—wave-particle duality—faced a significant challenge this year following a provocative reinterpretation of the classic double-slit experiment. While physics has long held that light simultaneously possesses particle and wave-like properties, researchers led by Celso Villas-Boas have proposed a model that explains interference patterns using only particles (photons). In the traditional double-slit experiment, light ...
