Electro-association of ultracold dipolar molecules into tetramer field-linked states
Goulven Quéméner, John L. Bohn, James F. E. Croft
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…
Sticking lifetime of ultracold CaF molecules in triplet interactions
Dibyendu Sardar, John L. Bohn
A six-dimensional potential energy surface is constructed for the spin-polarized triplet state of CaF-CaF by \textit{ab initio} calculations at the CCSD(T) level of theory, followe…
Four-body singlet potential energy surface for reactions of calcium monofluoride
Dibyendu Sardar, Arthur Christianen, Hui Li +1
A full six-dimensional Born-Oppenheimer singlet potential energy surface is constructed for the reaction CaF + CaF CaF + Ca using a multireference configuration i…
Electric field dependence of complex-dominated ultracold molecular collisions
Goulven Quéméner, James F. E. Croft, John L. Bohn
Recent experiments on ultracold non-reactive dipolar molecules have observed high two-body losses, even though these molecules can undergo neither inelastic, nor reactive (as they…
Anisotropic thermalization of dilute dipolar gases
Reuben R. W. Wang, John L. Bohn
We study collisional rethermalization in ultracold dipolar thermal gases, made intricate by their anisotropic differential cross sections. Theoretical methods are provided to deriv…
Magnetic Moments of Lanthanide van der Waals Dimers
Joseph McCann, John L. Bohn, Lucie D. Augustovičová
Loosely bound van der Waals dimers of lanthanide atoms, as might be obtained in ultracold atom experiments, are investigated. These molecules are known to exhibit a degree of quant…
