Abstract

A mean field calculation of the T\ensuremath→0 limit of the Hall conductance of electron-doped cuprates such as Pr_2\ensuremath-xCe_xCuO_4+\ensuremathδ is presented. The data are found to be qualitatively consistent with the reconstruction of the Fermi surface expected upon density wave ordering. The magnitude of the density wave gap is found to be large. The Hall resistance exhibits a nonanalyticity at the quantum critical point for density wave ordering, but the amplitude of the anomaly is found to be unobservably small. The quantum critical contribution to R_H(B) is determined. Quantitative discrepancies between calculation and data remain, suggesting that the experimental doping is not identical to the Ce concentration x.
