Driving superfluidity with photoassociation [PDF]
Optics Express, 2000 We theoretically examine photoassociation of a two-component Fermi degenerate gas. Our focus is on adjusting the atom-atom interaction, and thereby increasing the critical temperature of the BCS transition to the superfluid state.

Photoassociation of ultracold NaLi. [PDF]
Physical Chemistry Chemical Physics, 2017 We perform photoassociation spectroscopy in an ultracold 23Na-6Li mixture to study the c3Σ+ excited triplet molecular potential. We observe 50 vibrational states and their substructure to an accuracy of 20 MHz, and provide line strength data from ...

Photoassociation of Universal Efimov Trimers [PDF]
Journal of Physics B: Atomic, Molecular and Optical Physics, 2015 In view of recent experiments in ultracold atomic systems, the photoassociation of Efimov trimers, composed of three identical bosons, is studied utilizing the multipole expansion.

Photon echoes of molecular photoassociation [PDF]
SPIE Proceedings, 2004 Revivals of optical coherence of molecular photoassociation driven by two ultrashort laser pulses are addressed in the Condon approach. Based on textbook examples and numerical simulation of KrF excimer molecules, a prediction is made about an existence ...

Light forces in ultracold photoassociation [PDF]
Frontiers in Optics, 2006 We study the time-resolved photoassociation of ultracold sodium in an optical dipole trap. The photoassociation laser excites pairs of atoms to molecular states of large total angular momentum at high intensities (above 20 kW/cm$^{2}$).

Two-photon coherent control of femtosecond photoassociation [PDF]
Faraday Discussions, 2008 Photoassociation with short laser pulses has been proposed as a technique to create ultracold ground state molecules. A broad-band excitation seems the natural choice to drive the series of excitation and deexcitation steps required to form a molecule in

Modeling Photoassociative Spectra of Ultracold NaK + K. [PDF]
J Phys Chem A, 2023 A model for photoassociation of ultracold atoms and molecules is presented, and applied to the case of $^{39}$K and $^{23}$Na$^{39}$K bosonic particles. The model relies on the assumption that photoaossociation is dominated by long-range atom-molecule interactions, well outside the chemical bond region.

Formation of ultracold RbCs molecules by photoassociation [PDF]
Laser Physics, 2011 The formation of ultracold metastable RbCs molecules is observed in a double species magneto-optical trap through photoassociation below the ^85Rb(5S_1/2)+^133Cs(6P_3/2) dissociation limit followed by spontaneous emission.

Triatomic Photoassociation in an Ultracold Atom-Molecule Collision. [PDF]
Journal of Physical Chemistry A, 2022 Ultracold collisions of neutral atoms and molecules have been of great interest since experimental advances enabled the cooling and trapping of such species.
