Query: An Adiabatic Quantum Pump of Spin Polarized Current   We propose a mechanism by which an open quantum dot driven by two ac (radio
frequency) gate voltages in the presence of a moderate in-plane magnetic field
generates a spin polarized, phase coherent dc current. The idea combines
adiabatic, non-quantized (but coherent) pumping through periodically modulated
external parameters and the strong fluctuations of the electron wave function
existent in chaotic cavities. We estimate that the spin polarization of the
current can be observed for temperatures and Zeeman splitting energies of the
order of the single-particle mean level spacing.
