Butterfly Wing Pattern Emerges From Hundreds of Fractional Quantum Hall States in Ultra-Cold Magnetic Fields

Tokyo, Japan (SPX) Apr 29, 2026

Technological advances in confining electrons to two dimensions opened the door to observing the quantum Hall effect under high magnetic fields. In low-temperature electrical transport measurements, the Hall resistance forms plateaus at certain quantized values while longitudinal resistance is exponentially suppressed. When the Hall resistance of a state equals an integer or fractional multiple
