Quantum skyrmion Hall effect in f-electron systems
Physical Review Research, 2023 The flow of electric current through a two-dimensional material in a magnetic field gives rise to the family of Hall effects. The quantum versions of these effects accommodate robust electronic edge channels and fractional charges.

Dynamical competition between quantum Hall and quantum spin Hall effects [PDF]
Physical Review B, 2014 In this paper we investigate the occurrence of quantum phase transitions in topological systems out of equi- librium. More specifically, we consider graphene with a sizable spin-orbit coupling, irradiated by circularly- polarized light. In the absence of light, the spin-orbit coupling drives a quantum spin Hall phase where edge currents with opposite ...

Quantum spin Hall phase in 2D trigonal lattice
Nature Communications, 2016 Whilst different models describing the two-dimensional quantum spin Hall effect exist, very few experimental systems have been realized in which to test theory.

Magic in twisted transition metal dichalcogenide bilayers
Nature Communications, 2021 The e moiré superlattice in twisted 2D structures becomes a highly tunable platform of strongly correlated electron systems. Here, the authors predict rich physics at small twist angles in twisted transition metal dichalcogenide bilayers, including a ...

Fractional spin for quantum Hall effect quasiparticles [PDF]
Nuclear Physics B, 1995 We investigate the issue of whether quasiparticles in the fractional quantum Hall effect possess a fractional intrinsic spin. The presence of such a spin $S$ is suggested by the spin-statistics relation $S= /2 $, with $ $ being the statistical angle, and, on a sphere, is required for consistent quantization of one or more quasiparticles.

The quantum Hall effect: spin-charge locking [PDF]
Malaysian Journal of Fundamental and Applied Sciences, 2011 In two-dimensional electron gas when a large magnetic field is applied in one direction and an electric field perpendicular to it, there is a current in a direction perpendicular to both. This current is called the Hall effect. It remained without quantization until 1980 when it was found that the quantization leads to correct measurement of h/e2 ...

Dynamical picture of spin Hall effect based on quantum spin vorticity theory
AIP Advances, 2016 It is proposed that the dynamical picture of the spin Hall effect can be explained as the generation of the spin vorticity by the applied electric field on the basis of the “quantum spin vorticity theory”, which describes the equation of motion of local ...
