MAGNETOMETER BASED ON ATOMIC COHERENCE AND POSSIBLE APPLICATION TO THE SEARCH FOR P-VIOLATING AND T-VIOLATING PERMANENT ELECTRIC-DIPOLE MOMENTS OF ATOMS

A new approach to the experimental search for P and T violating perman ent electric dipole moments (EDMS) in atoms is proposed. The high disp ersion of a phase coherent atomic medium at a point of electromagnetic ally induced transparency is used to detect linear Starkshifts associa ted with an atomic EDM in a highly sensitive interferometric measureme nt. Possible noise sources are analysed and estimates are given for th e device sensitivity.
