Query: Superconductor-insulator quantum critical point in 1+\epsilon dimensions   A system of spinless fermions in $d=1+\epsilon$ dimensions, at
zero-temperature and in random potential is studied using the perturbative
renormalization group to first order in disorder and to second order in
interaction. We find a superconductor-to- Anderson insulator quantum fixed
point at an infinitesimal value of disorder and calculate the correlation
length and the dynamical exponents to the lowest order in $\epsilon$ and in
interaction. The scaling of conductivity with temperature and the behavior of
characteristic temperature scales on both sides of the transition is
determined. The model may have relevance for a p-wave superconductor at low
temperatures in strongly disordered media.
