Query: Energy level statistics in weakly disordered systems: from quantum to
  diffusive regime   We calculate two-point energy level correlation function in weakly disorderd
metallic grain with taking account of localization corrections to the universal
random matrix result. Using supersymmetric nonlinear sigma model and exactly
integrating out spatially homogeneous modes, we derive the expression valid for
arbitrary energy differences from quantum to diffusive regime for the system
with broken time reversal symmetry. Our result coincides with the one obtained
by Andreev and Altshuler [Phys. Rev. Lett. 72, 902 (1995)] where homogeneous
modes are perturbatively treated.
