Graphene Defies Fundamental Law of Physics

Swift Summary

• Researchers at the Department of physics, IISc, and collaborators from Japan have detected a quantum fluid of electrons in graphene.
• the study reveals an inverse relationship between electrical conductivity and thermal conductivity in graphene, defying the Wiedemann-Franz law typically observed in metals.
• This behavior is associated with the “Dirac fluid” state, where electrons behave collectively like a minimally viscous liquid near the Dirac point-a unique electronic tipping point when graphene acts neither as a metal nor an insulator.
• Results establish graphene as a platform to explore high-energy physics phenomena such as black-hole thermodynamics and quark-gluon plasma dynamics under laboratory conditions.
• Potential applications include advancements in quantum sensors for amplifying weak signals and detecting faint magnetic fields.
