CP-violating magnetic moments of atoms and molecules

Supersymmetry (SUSY) is a basic, yet experimentally unproven, concept of particle physics. Finding evidence for SUSY is a goal of the soon-to-be-operational Large Hadron Collider. Alternatively, SUSY can be revealed in atomic-physics quest for electric dipole moment of the electron (eEDM). Already the present limit on eEDM  is comparable to predictions of the ``naive'' SUSY models. In this talk I will propose a new route to even more sensitive table-top search for SUSY.

Recently we introduced a concept of CP-violating (T-odd,P-odd) atomic and molecular magnetic moments and related it to the eEDM. We distinguish between permanent and thermodynamically averaged CP-odd magnetic moments. The moments are directed along the molecular axis. We propose to employ polarized molecular radicals frozen in a rare-gas matrix and measure the eEDM-induced magnetic field generated by the sample.  Conservative estimates project that the present limit on eEDM can be improved by several
orders of magnitude.
