Twisted Bilayer Graphene: Magic-Angle Simulator

Rotate the top graphene sheet relative to the bottom one and watch three linked views respond in real time: a top-down moiré render of the two honeycomb lattices, a model electronic band-structure chart that flattens dramatically only near the ≈1.1° magic angle, and a resistance-vs-temperature curve that only drops toward zero — mimicking a superconducting-like transition — when both the twist angle sits near that magic angle and the electron filling sits near a correlated "dome" region. Away from the magic angle, the same filling and temperature controls leave the material behaving like an ordinary dispersive-band metal.
