Abstract: The A phase of 3He is a chiral superfluid that spontaneously breaks parity and time-reversal symmetries. This was beautifully demonstrated by the observation of an anomalous Hall mobility of electron bubbles by the RIKEN group. We present the theory of the anomalous Hall effect for negative ions in superfluid 3He-A based on a full quantum mechanical treatment of multiple scattering of Bogoliubov quasiparticles by ions embedded in the chiral superfluid. Quantum interference leads to the transverse force on the ions. Our results are in quantitative agreement with the RIKEN experiments, providing a microscopic view of the underlying processes responsible for the anomalous Hall effect.
