Intercombination line photoassociation spectroscopy of ${}^{87}$Rb${}^{170}$Yb
, 2023 We report on the first observation of photoassociation near the ${}^2 S _\frac 1 2 + {}^3P_1$-asymptote in a mixture of ${}^{87}$Rb and ${}^{170}$Yb.

Theoretical studies of photoassociation in ultracold metastable helium
, 2009 Line shifts and line shapes for photoassociation of spin-polarised metastable helium to long-range vibrational states in the J = 1,0+u potential dissociating to the 2s3S1 + 2p 3P0 limit are studied using a nonperturbative multichannel calculation valid ...

Intensity Dependence of Photoassociation in a Quantum Degenerate Atomic Gas
, 2003 We have measured the intensity dependent rate and frequency shift of a photoassociation transition in a quantum degenerate gas of Li7. The rate increases linearly with photoassociation laser intensity for low intensities, whereas saturation is observed ...

Enhancing photoassociation rates by nonresonant-light control of shape resonances [PDF]
, 2020 Photoassociation, assembling molecules from atoms using laser light, is limited by the low density of atom pairs at sufficiently short interatomic separations. Here we show that nonresonant light with intensities of the order of 10 10 W/cm 2 modifies the

Photoassociation spectroscopy of purely long-range krypton molecules [PDF]
, 2009 Photoassociation spectra for purely long-range (PLR) krypton molecules are both computed and measured. The photoassociation laser is tuned just red of the 5s[3/2]2-5p[5/2]2 transition at 810.6 nm, over a frequency range in which fourteen different PLR ...

Photoassociation of Trilobite Rydberg Molecules via Resonant Spin-Orbit Coupling [PDF]
, 2017 We report on a novel method for the photoassociation of strongly polar trilobite Rydberg molecules. This exotic ultralong-range dimer, consisting of a ground-state atom bound to the Rydberg electron via electronneutral scattering, inherits its polar ...

Precision spectroscopy of ultracold ^{86}Sr_{2} halo molecules
Physical Review ResearchWe demonstrate the creation and field-free precision spectroscopy of ultracold ^{86}Sr_{2} molecules in the halo regime, where vibrational binding energies are dominated by long-range interactions.

Closed-channel parameters of Feshbach resonances
SciPost PhysicsThis work investigates how the closed channel of a Feshbach resonance is characterised by experimental observables. Surprisingly, it is found that the two-body observables associated with the Feshbach resonance can be insensitive to the properties of the

A pathway to ultracold bosonic 23Na39K ground state molecules
New Journal of Physics, 2019 We spectroscopically investigate a pathway for the conversion of ^23 Na ^39 K Feshbach molecules into rovibronic ground state molecules via stimulated Raman adiabatic passage.

Photoassociation of a Bose-Einstein Condensate near a Feshbach Resonance
, 2008 We measure the effect of a magnetic Feshbach resonance (FR) on the rate and light-induced frequency shift of a photoassociation resonance in ultracold Li7.
