The Quantum Hall effect (QHE) is one of the most important discoveries in physical sciences. Due to the one-dimensional (1-D) dissipationless edge states, QHE exhibits exotic transport properties with ...

By fitting this equation to the experimental data x(t), with the Chern number being the only fit parameter, we obtain an experimental value for the Chern number of the lowest band Here we averaged ...

In topological materials, electrons can display behavior that is fundamentally differentfrom that in 'conventional' matter, and the magnitude of many such 'exotic' phenomena is directly proportional ...

We note that additional calculations show that these phases remain robust under variations in the number of layers in one sheet, e.g., n b. This can already be seen from the fact that the ...

Topology, a branch of mathematics classifying geometric objects, has been exploited by physicists to predict and describe unusual quantum phases: the topological states of matter. These intriguing ...
