Graphene Electrons Flow as Frictionless Liquid, Defying Physics

Scientists have observed electrons in graphene behaving as a nearly frictionless liquid, a phenomenon that defies a core law of physics. The finding marks a significant experimental breakthrough in condensed matter research, demonstrating that graphene's tightly bound carbon lattice enables an exotic quantum state not seen in conventional conductors. In standard materials, electron flow is governed by classical resistance principles where collisions with the lattice dissipate energy. In graphene, electrons instead interact primarily with each other rather than the lattice, entering a hydrodynamic regime where they move collectively like a viscous fluid with near-zero friction. This behavior violates the Wiedemann-Franz law, which links electrical and thermal conductivity in normal metals, signaling a departure from established transport physics. The practical consequence is electron flow that loses almost no energy to heat, a property that could underpin ultra-efficient transistors, low-dissipation interconnects, and quantum computing components. The immediate watch point is whether this state can be reliably reproduced and stabilized at temperatures relevant to real-world device fabrication.
