, 2011 We study the effects of a static electric field on the photoassociation of a heteronuclear atom-pair into a polar molecule. The interaction of permanent dipole moment with a static electric field largely affects the ground state continuum wave function ...

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

Feshbach-optimized photoassociation of ultracold $^6$Li$^{87}$Rb molecules with short pulses
, 2013 Two-color photoassociation of ground state $^6$Li$^{87}$Rb molecules via the $\mathrm{B}^1\Pi$ electronic state using short pulses near a magnetic Feshbach resonance is studied theoretically. A near-resonant magnetic field is applied to mix the hyperfine

Combination of a magnetic Feshbach resonance and an optical bound-to-bound transition
, 2009 We use laser light near resonant with an optical bound-to-bound transition to shift the magnetic field at which a Feshbach resonance occurs. We operate in a regime of large detuning and large laser intensity. This reduces the light-induced atom-loss rate

Role of Bose enhancement in photoassociation [PDF]
, 2000 We discuss the role of Bose enhancement of the dipole matrix element in photoassociation, using stimulated Raman adiabatic passage as an example. In a nondegenerate gas the time scale for coherent optical transients tends to infinity in the thermodynamic

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.

, 2012 We report the first observation of photoassociation to the 2(1)Sigma(g)(+) state of 85Rb2 . We have observed two vibrational levels (v'=98, 99) below the 5s1/2+5p1/2 atomic limit and eleven vibrational levels (v'=102-112) above it. The photoassociation---

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.
