Abstract: The quantum phenomenon of spectral flow which has been observed in laboratorysuperfluids, such as 3He-B, controls the drift velocity of proton type IIsuperconductor vortices in the liquid core of a neutron star and so determinesthe rate at which magnetic flux can be expelled from the core to the crust. Inthe earliest and most active phases of the anomalous X-ray pulsars andsoft-gamma repeaters, the rates are low and consistent with a large fraction ofthe active crustal flux not linking the core. If normal neutrons are present inan appreciable core matter-density interval, the spectral flow force limitsflux expulsion in cases of rapid spin-down, such as in the Crab pulsar or inthe propeller phase of binary systems.
