Query: Flavors of noise in magnetic Weyl semimetals   Transport in magnetic Weyl semimetals (WSMs) generally involves three degrees
of freedom -- charge, valley, and spin. In this work, we systematically
investigate the magnetic noise induced by the fluctuations of the charge
current, the valley (axial) current, and the magnetic order. We show that these
three flavors of the magnetic noise have distinctively different spectral
characters. Our work provides a theoretical guidance for the noninvasive study
of valley transport in magnetic WSMs by magnetic noise spectroscopy, for
example, using nitrogen-vacancy centers. Our approach could also be generalized
to discuss WSMs with other types of broken symmetries and topological
semimetals in general.
