My recent efforts have been devoted to developing methods for measuring the electric dipole moments (EDM) of the electron and the proton. These moments are known to be very small. Any measureably large EDM would be evidence for violation of both parity (P) and time reversal (T) invariance. Such violations are expected to be associated with the observed imbalance of particles and anti-particles in the present-day universe. Appreciable deviation from zero could indicate violation of the “standard model” of elementary particle physics. There are numerous experimental challenges. The immediate plan, in collaboration with physicists at Jefforson Lab in Virginia and at U.N.M, is to demonstrate (non-destructive) Stern-Gerlach polarimetry, both transverse and longitudinal, at Jefferson Lab.
