我们证明，同时作用于极性顺磁（和可极化）分子的全等电场、磁场和非共振光场提供了放大和控制随后分子态方向性的可能性，这超越了双场组合或单独单场中可用的分子态。这些三重场效应的核心是通过叠加在光场上的磁场来提升投影量子数 M 的简并性，以及随后由于光场甚至弱静电场而导致的“双重”（对于 M ≠ 0 ?> 的状态）隧道双峰成员的耦合。
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 ≠ 0 ?> ) tunneling doublets due to the optical field by even a weak electrostatic field.
