We study the van der Waals interaction between Rydberg alkali-metal atoms with fine structure ($n^2L_j$; $L\leq 2$) and heteronuclear alkali-metal dimers in the ground rovibrational state ($X^1\Sigma^+$; $v=0$, $J=0$). We compute the associated $C_6$ dispersion coefficients of atom-molecule pairs involving $^{133}$Cs and $^{85}$Rb atoms interacting with KRb, LiCs, LiRb, and RbCs molecules. The obtained dispersion coefficients can be accurately fitted to a state-dependent polynomial $O(n^7…

Short-range photoassociation of LiRb
We have observed short-range photoassociation of LiRb to the two lowest vibrational states of the $d\,^3\Pi$ potential. These $d\,^3\Pi$ molecules then spontaneously decay to vibrational levels of
Controlling Rydberg atom excitations in dense background gases
We discuss the density shift and broadening of Rydberg spectra measured in cold, dense atom clouds in the context of Rydberg atom spectroscopy done at room temperature, dating back to the experiments
Observation of ultralong-range Rydberg molecules
TLDR
The spectra of the vibrational ground state and of the first excited state of the Rydberg molecule, the rubidium dimer Rb(5s)–Rb(ns), agree well with simple model predictions and allow us to extract the s-wave scattering length for scattering between the R Sydberg electron and the ground-state atom, Rb (5s), in the low-energy regime.
Electric dipole polarizabilities of Rydberg states of alkali-metal atoms
Calculations of the static electric-dipole scalar and tensor polarizabilities are presented for two alkali atoms, Rb and Cs, for the $nS$, $nP_{1/2, 3/2}$, and $nD_{3/2, 5/2}$ states with large

Creation of ultracold ^{87}Rb^{133}Cs molecules in the rovibrational ground state.
TLDR
A sample of over 1000 ultracold ^{87}Rb^{133}Cs molecules in the lowest rovibrational ground state is created by magnetoassociation on an interspecies Feshbach resonance followed by stimulated Raman adiabatic passage (STIRAP).

TLDR
It is found that for all alkali pairs, the parallel and perpendicular components of the ground state polarizabilities at the equilibrium distance R(e) scale as (R(e))(3), which can be related to a simple electrostatic model of an ellipsoidal charge distribution.

Long-range interactions between ultracold atoms and molecules including atomic spin-orbit.
TLDR
The long-range electrostatic interactions between a ground-state homonuclear alkali-metal dimer and an excited alkali -metal atom taking into account its fine-structure are investigated theoretically and various regimes induced by the magnitude of the atomic spin-orbit are extended.
