Figure 1: Schematics of the all-optical experimental set-up used to generate a uniform artificial magnetic field and the Chern-number measurement. Figure 2: Energy spectra and topology of the Bloch ...

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

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

Quantum Hall effect (QHE) plays an important role in materials science and precision measurement. Due to the dissipationless edge states, QHE exhibits exotic transport properties with quantized Hall ...

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 ...
