Abstract

We propose a method that uses a static magnetic field to enable direct optical excitation of forbidden electric dipole transitions that are otherwise prohibitively weak. The method is based on mixing of atomic states by a static magnetic field. The method can also be viewed as a limiting case of two-photon spectroscopy, where the frequency of one of the fields -- a magnetic field, in this case -- is equal to zero. Using this method, we calculate that an optical lattice-based ytterbium standard could achieve a fractional frequency uncertainty of less than 10-17 for the metrologically preferred even isotope.
