Sensing a THz electric field with a molecular ion clock
Résumé
This contribution proposes a new method for THz-wave detection that exploits the sensitivity to external fields of the transitions of accurate molecular ion clocks. A THz electric field, off-resonantly coupled to the HD+ energy levels, may be characterized from the comparison between the measurements of the lighshifts induced on a two-photon rovibrational transition probed on cold trapped molecular ions, and the theoretical predictions of the molecular ion theory. A set of six independent lightshift measurements may be converted into the amplitudes and the phases of the Cartesian components of the THz electric field in the laboratory frame.
