Abstract: We measure the hyperfine structure of $nP_{1/2}$ Rydberg states using mm-wave spectroscopy on an ensemble of laser-cooled $^{85}$Rb atoms. Systematic uncertainties in our measurement from the Zeeman splittings induced by stray magnetic fields and dipole-dipole interactions between two Rydberg atoms are factored in with the obtained statistical uncertainty. Our final measurement of the $nP_{1/2}$ hyperfine coupling constant is $A_{\text{hfs}}=1.443(31)$~GHz. This measurement is useful for studies of long-range Rydberg molecules, Rydberg electrometry, and quantum simulation with dipole-dipole interactions involving $nP_{1/2}$ atoms.

Analytical Correlation in the H$_{2}$ Molecule from the Independent Atom Ansatz [49.1574468325115]
The total energy functional correctly dissociates the H-H bond and yields absolute errors of 0.002 $rA$, 0.19 eV, and 13 cm-1$ relative to experiment at the tight binding computational cost. The chemical bond formation is attributed to the Heitler-London resonance of quasi-orthogonal atomic states with no contributions from kinetic energy or charge accumulation in the bond.

Rapid generation of all-optical $^{39}$K Bose-Einstein condensates using a low-field Feshbach resonance [58.720142291102135]
We investigate the production of all-optical $39$K Bose-Einstein condensates with different scattering lengths using a Feshbach resonance near $33$ G. We are able to produce fully condensed ensembles with $5.8times104$ atoms within $850$ ms evaporation time at a scattering length of $232. Based on our findings we describe routes towards high-flux sources of ultra-cold potassium for inertial sensing.

We study ultracold long-range collisions of alkali-metal dimers with a reservoir gas of alkalimetal Rydberg atoms in a two-photon laser excitation scheme. We show that the two-photon photoassociation (PA) of the atom-molecule pair into a long-range bound trimer state is efficient over a broad range of atomic Rydberg channels.
