Hall effect and magnetoresistance in copper oxide metals.

We present the solution of the Boltzmann equation with an applied electric and magnetic field including skew scattering in the collision operator. The observed unusual temperature dependences of the Hall resistance and the magnetoresistance as well as the frequency dependence of the Hall resistance in the normal state of copper oxide metals is shown to arise if the skew scattering rate diverges as T→0. The implication of this phenomenological result for the microscopic theory of copper oxide metals is that the chiral response function ~proportional to the magnetic field! has a singularity in the limit of zero energy and temperature.
