“…This helps to calibrate the probable accuracy of the calculations for other alkali-metal dimers. The fitted value c 4 = 19.0(1) kHz removes one of the two largest sources of error in our recent determination of the binding energy D 0 of 87 Rb 133 Cs in its rovibrational ground state [38]; the zero-field hyperfine energy of the M F = 5 state is ( 21 4 )c 4 , which increases from 90(30) kHz in Ref. [38] to 99.9 (6) [27]) to obtain values of the "bare" nuclear g factors 1.836(3) and 0.738 (1).…”

“…Dipolar molecules near absolute zero may enable improved precision measurements of fundamental constants (Baron et al, 2014;Molony et al, 2016) as well as new schemes in quantum computing (DeMille, 2002) and quantum simulation of condensed matter materials (Baranov et al, 2012).…”

“…Our experimental apparatus and the method for creating ultracold RbCs molecules have been discussed in previous publications [40,[95][96][97][98][99]. In this work, we create a sample of up to ∼3000 RbCs molecules in their absolute ground state at a temperature of 1.5(1) μK by magnetoassociation on an interspecies Feshbach resonance [96], followed by transfer to the rovibronic and hyperfine ground state by stimulated Raman adiabatic passage (STIRAP) [40,99].…”

The magnetoassociation is performed in a crossed optical dipole trap (ODT) operating at λ = 1550 nm, but the STIRAP is performed in free space to avoid spatially varying ac Stark shifts [98,99]. A uniform magnetic field of 181.5 G is present following magnetoassociation and throughout the STIRAP.…”
