Production of ultracold ground-state LiRb molecules by photoassociation through a resonantly coupled state [PDF]

, 2016
We report on a resonantly coupled 2(1)-4(1) photoassociation resonance in LiRb. This pair of states displays interesting decay physics that hint at interference-like effects caused by two different decay paths.

Closed-channel parameters of Feshbach resonances

SciPost Physics
This 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

Improved LeRoy-Bernstein near-dissociation expansion formula. Tutorial application to photoassociation spectroscopy of long-range states

, 2003
NDE (Near-dissociation expansion) including LeRoy-Bernstein formulas are improved by taking into account the multipole expansion coefficients and the non asymptotic part of the potential curve.

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.

Formation of deeply bound ultracold Sr_2 molecules by photoassociation near the ^1S + ^3P_1 intercombination line

, 2012
We predict feasibility of the photoassociative formation of Sr_2 molecules in arbitrary vibrational levels of the electronic ground state based on state-of-the-art ab initio calculations. Key is the strong spin-orbit interaction between the c^3\Pi_u, A^1\

Cs D2 line laser (852.1 nm) pumped by the photoassociation of Cs-Ar, Cs-Kr, and Cs-Xe collision pairs: Impact of rare gas partner on threshold and efficiency

Applied Physics Letters, 2018
Cs atomic lasers, operating on the D2 line and pumped by the photoassociation of Cs-rare gas thermal collision pairs, have been examined in mixtures of Cs vapor with Ar, Kr, or Xe. Photoexcitation of the B 2Σ+ − X 2Σ+ molecular transition (i.e., the blue

Magnetic control of ultra-cold 6Li and 174Yb(3P2) atom mixtures with Feshbach resonances

New Journal of Physics, 2015
We theoretically evaluate the feasibility to form magnetically-tunable Feshbach molecules in collisions between fermionic ^6 Li atoms and bosonic metastable ^174 Yb( ^3 P _2 ) atoms.

Photoassociation dynamics in a Bose-Einstein condensate

, 2004
A dynamical many body theory of single color photoassociation in a Bose-Einstein condensate is presented. The theory describes the time evolution of a condensed atomic ensemble under the influence of an arbitrarily varying near resonant laser pulse ...

Coherent Manipulation of Orbital Feshbach Molecules of Two-Electron Atoms

Physical Review X, 2019
Ultracold molecules have experienced increasing attention in recent years. Compared to ultracold atoms, they possess several unique properties that make them perfect candidates for the implementation of new quantum-technological applications in several ...
