For the first time, researchers have directly observed electrons in graphene acting as a near-perfect quantum fluid. Using ultra-clean graphene samples, the IISc team uncovered an unexpected separation between heat and charge transport which breaks the long-accepted Wiedeman-Franz law.
At the “Dirac point,” electrons in graphene no longer behave like conventional particles but instead flow as a low-viscosity quantum liquid, resembling exotic matter such as quark-gluon plasma.
This result does more than revise a page in physics textbook but instead it creates a framework for exploring black hole physics and quantum entanglement under laboratory conditions, with potential applications in future quantum sensing technologies.
