Graphene Reveals Electrons Flowing as a Frictionless Fluid
By Quantum Server Networks Graphene, the celebrated “wonder material” composed of a single layer of carbon atoms, has once again defied expectations. Researchers at the Indian Institute of Science (IISc), in collaboration with the National Institute for Materials Science in Japan, have observed electrons in graphene behaving like a frictionless quantum fluid . The discovery, reported in Nature Physics and summarized by Phys.org , challenges established textbook rules and opens new avenues for quantum technologies.

Credit: Aniket Majumdar Breaking the Wiedemann–Franz Law In ordinary metals, the Wiedemann–Franz law states that electrical and thermal conductivity are proportional: if electrons carry charge efficiently, they should also carry heat efficiently. Yet in ultra-clean graphene samples, the IISc team observed the opposite. As electri...
