摘要
Quantum Hall effects have remained at the forefront of condensed matter physics research for decades,earning three Nobel Prizes in physics as a testament to their significance.In 1980,von Klitzing et al.discovered discrete Hall conductance_(xy)=e^(2)/h g in a two-dimensional electron gas subjected to a magnetic field,where n represents the number of occupied Landau levels.This groundbreaking discovery is famously known as the integer quantum Hall effect and has been generalized in both fractional and anomalous ways(Fig.S1 online).
