WebJan 14, 2015 · Moreover, we study the chiral electric waves led by the fluctuations of the vector and axial chemical potentials along with the chiral electric separation effect, where a density wave propagates along the applied electric field. Combining with the normal/chiral Hall effects, the fluctuations of chemical potentials thus result in Hall density waves. WebMar 22, 2024 · The chiral anomaly (CA) is one the most remarkable topological properties in Weyl semimetals (WSMs). Here, the authors investigate the second-order nonlinear planar Nernst and thermal Hall effects in WSMs, manifested by thermal CA with coplanar thermal gradient and magnetic field. With intrinsic chiral chemical potential, these …
WebMar 4, 2024 · Chiral Hall effect in a chiral Heisenberg magnet. A 2D system of side-length L containing 100 × 100 spins is simulated at T = 1 K using the Spirit code. Starting from the polarized state at H z = − 4 T, the magnetic field is increased step by step. (a) At H z = 0.57 T the magnetization starts to switch. Shown is the density of the CHE which ... WebUnlike the quantum Hall effect, this “chiral anomaly” exists in both the quantum and semiclassical transport limits (8, 15, 17, 18, 19). The phenomenon requires two important ingredients. In the semiclassical limit, the first is a magnetic field–induced coupling between the chiral and the total charge densities via Berry curvature. This ...
WebMay 13, 2010 · The anomalous Hall effect (AHE) occurs in solids with broken time-reversal symmetry, typically in a ferromagnetic phase, as a consequence of spin-orbit coupling. Experimental and theoretical studies of the AHE are reviewed, focusing on recent developments that have provided a more complete framework for understanding this … WebCan’t a truly one-dimensional system just show the same behavior of the chiral edge state of the quantum Hall effect?
