Directional properties of polar paramagnetic molecules subject to congruent electric, magnetic and optical fields
Abstract
We show that congruent electric, magnetic and non-resonant optical fields acting concurrently on a polar paramagnetic (and polarizable) molecule offer possibilities to both amplify and control the directionality of the ensuing molecular states that surpass those available in double-field combinations or in single fields alone. At the core of these triple-field effects is the lifting of the degeneracy of the projection quantum number M by the magnetic field superimposed on the optical field and a subsequent coupling of the members of the ‘doubled’ (for states with $M\ne 0$ ) tunneling doublets due to the optical field by even a weak electrostatic field.
