- Scientists observed electrons in graphene behaving like a nearly perfect quantum fluid, challenging the Wiedemann-Franz law.
- Ultra-clean graphene samples showed a surprising decoupling of heat and charge transport, with a deviation factor of more than 200 at low temperatures.
- This exotic behavior emerges at the 'Dirac point,' where graphene electrons flow like a Dirac fluid, similar to quark-gluon plasma.
- The discovery opens new avenues for studying black holes, quantum entanglement, and could power next-gen quantum sensors.
- Graphene's minimal viscosity near the Dirac point makes it an ideal platform for high-energy physics and astrophysics research.
