Universal fluctuation of the Hall conductance in a random magnetic field
Universal fluctuation of the Hall conductance in a random magnetic field
We show that the rms fluctuation of the antisymmetric part of the Hall conductance of a planar mesoscopic metal in a random magnetic field with zero average is universal; it is of the order of ${\mathit{e}}^{2}$/h, independent of both the amplitude of the random magnetic field and the diffusion coefficient …
