In 2D materials with inverted bands and Mexican-hat dispersion, extrinsic skew-scattering spin Hall current exceeds intrinsic Berry-curvature SHC and displays non-monotonic Fermi-energy dependence with possible sign change.
Quasi-periodic driving of a four-level system creates temporal analogs of quantum spin Hall and higher-order topological insulators, yielding quantized energy exchange rates between drives due to synthetic edge or corner modes.

Topological energy pumping in a quasi-periodically driven four-level system
Quasi-periodic driving of a four-level system creates temporal analogs of quantum spin Hall and higher-order topological insulators, yielding quantized energy exchange rates between drives due to synthetic edge or corner modes.
