Query: Quantum Critical Behavior of Disordered Superfluids   The quantum critical behavior of an interacting, non-relativistic Bose theory
with quenched disorder randomly distributed in space is investigated. The
renormalization group is carried out in a double $\epsilon$ expansion, where
one $\epsilon$ is the deviation of the effective space-time dimensionality from
4, while the other denotes the number of time dimensions. The disordered
theory, which displays localization in the superfluid state, is shown to
possess an infrared stable fixed point.
