Abstract:

The Hall resistivity ($\rho_{xy}$) is discussed in an electronic system with sufficient Rashba coupling and in the absence of external magnetic field. It is found that the off-diagonal component of the resistivity is determined by the reactive part (real part) of the inverse dielectric functions. This is in contrast to any other electrical transport including magnetotransport where all resistivity components (both diagonal and off-diagonal) are determined by the absorptive part (imaginary part) of the inverse dielectric functions.
