Electro-association of ultracold dipolar molecules into tetramer field-linked states

Abstract

The presence of electric or microwave fields can modify the long-range forces between ultracold dipolar molecules in such a way as to engineer weakly-bound states of molecule pairs. These so-called field-linked states [Avdeenkov et al., Phys. Rev. Lett. 90, 043006 (2003), Lassablière et al., Phys. Rev. Lett. 121, 163402 (2018)], in which the separation between the two bound molecules can be orders of magnitude larger than the molecules themselves, have been observed as resonances in scattering experiments [Chen et al., Nature 614, 59 (2023)]. Here, we propose to use them as tools for the assembly of weakly-bound tetramer molecules, by means of ramping an electric field, the electric-field analog of magneto-association in atoms. This ability would present new possibilities for constructing ultracold polyatomic molecules.
