High-Chern-number and high-temperature quantum Hall effect without Landau levels
High-Chern-number and high-temperature quantum Hall effect without Landau levels
The quantum Hall effect (QHE) with quantized Hall resistance of h/νe2 started the research on topological quantum states and laid the foundation of topology in physics. Since then, Haldane proposed the QHE without Landau levels, showing nonzero Chern number |C| = 1, which has been experimentally observed at relatively low …
