Princeton physicists accidentally discovered and directly visualized Hofstadter’s butterfly—a theoretical fractal pattern of electron energy levels predicted in 1976—using scanning tunneling microscopy on twisted bilayer graphene, revealing not only the long-sought fractal energy spectrum but also new quantum phenomena driven by electron interactions beyond Hofstadter’s original calculations.
A groundbreaking discovery in quantum physics has revealed a novel electronic state in twisted graphene layers, where electrons exhibit the paradoxical behavior of being simultaneously frozen yet capable of conducting current along edges without resistance.
Magnets and superconductors don’t normally get along, but a new study shows that ‘magic-angle’ graphene is capable of producing both superconductivity and ferromagnetism, which could be useful in quantum computing.
Physicists at the University of Basel have developed a minuscule instrument able to detect extremely faint magnetic fields.
Max Planck Institute for the Structure and Dynamics of Matter (MPSD) scientists have discovered a pioneering laser-driven approach to generate a topological state in graphene.
Researchers at Aalto University have yet reported ultrawide Josephson junctions (up to 80 μm wide) based on chemical-vapor-deposition graphene where the critical current was found to be uniformly distributed in the direction perpendicular to the current.
