Bounds on Microscopic Physics from P and T Violation in Atoms and   Molecules
  Atomic and molecular electric dipole moments are calculated within the minimal supersymmetric standard model. Present experiments already provide strong bounds on the combination of phases responsible for the dipole moments of the neutron and closed shell atoms. For a supersymmetry breaking scale of 100 GeV, these phases must be smaller than $ \sim 10^{-2}$.
