High-precision spectroscopy of ultracold molecules in an optical lattice
New Journal of Physics, 2015 The study of ultracold molecules tightly trapped in an optical lattice can expand the frontier of precision measurement and spectroscopy, and provide a deeper insight into molecular and fundamental physics.

Feshbach-resonant Raman photoassociation in a Bose-Einstein condensate
, 2011 We model the formation of stable heteronuclear molecules via pulsed Raman photoassociation of a two-component Bose-Einstein condensate near a strong Feshbach resonance, for both counterintuitive and intuitive pulse sequencing.

Photoassociation inside an optical dipole trap: absolute rate coefficients and Franck-Condon factors
, 2004 We present quantitative measurements of the photoassociation of cesium molecules inside a far-detuned optical dipole trap. A model of the trap depletion dynamics is derived which allows to extract absolute photoassociation rate coefficients for the ...

Detecting high-density ultracold molecules using atom–molecule collision
New Journal of Physics, 2013 Utilizing single-photon photoassociation, we have achieved ultracold rubidium molecules with a high number density that provides a new efficient approach toward molecular quantum degeneracy.

Optimizing the photoassociation of cold atoms by use of chirped laser pulses
, 2004 Photoassociation of ultracold atoms induced by chirped picosecond pulses is analyzed in a non-perturbative treatment by following the wavepackets dynamics on the ground and excited surfaces.

Bose-Stimulated Raman Adiabatic Passage in Photoassociation [PDF]
Physical Review Letters, 2000 We analyze coherent two-color photoassociation of a Bose-Einstein condensate, focusing on stimulated Raman adiabatic passage (STIRAP) in free-bound-bound transitions from atoms to molecules. This problem is of particular interest since STIRAP is predicted to be necessarily absent in the nondegenerate case [Javanainen and Mackie, Phys. Rev.

Saturation in heteronuclear photoassociation of 6Li7Li
, 2002 We report heteronuclear photoassociation spectroscopy in a mixture of magneto-optically trapped 6Li and 7Li. Hyperfine resolved spectra of the vibrational level v=83 of the singlet state have been taken up to intensities of 1000 W/cm^2. Saturation of the

Quantum defect theory description of weakly bound levels and Feshbach resonances in LiRb
New Journal of Physics, 2015 The multichannel quantum defect theory (MQDT) in combination with the frame transformation (FT) approach is applied to model the Fano–Feshbach resonances measured for ^7 Li ^87 Rb and ^6 Li ^87 Rb Marzok et al (2009 Phys. Rev. A http://dx.doi.org/10.1103/

Theory of Combined Photoassociation and Feshbach Resonances in a Bose-Einstein Condensate
, 2009 We model combined photoassociation and Feshbach resonances in a Bose-Einstein condensate, where the shared dissociation continuum allows for quantum interference in losses from the condensate, as well as a dispersive-like shift of resonance.
