Query: Absence of Hall effect due to Berry curvature in phase space   Transverse current due to Berry curvature in phase space is formulated based
on the Boltzmann equations with the semiclassical equations of motion for an
electron wave packet. It is shown that the Hall effect due to the phase space
Berry curvature is absent because the contributions from "anomalous velocity"
and "effective Lorentz force" are completely cancelled out.
