Graphene just broke a fundamental law of physics

Researchers at the Indian Institute of Science observed electrons in graphene behaving as an almost perfect fluid, violating the Wiedemann-Franz law by over 200 times. This reveals a significant decoupling between electrical and thermal conductivity at the material's "Dirac point," where electrons move collectively like a low-viscosity liquid. The discovery confirms long-theorized quantum behavior previously undetectable due to material imperfections, establishing graphene as an ideal platform for studying exotic quantum phenomena and potentially developing ultrasensitive quantum sensors.
