Theoretical Calculation of Ground and Electronically Excited States of MgRb⁺ and SrRb⁺ Molecular Ions: Electronic Structure and Prospects of Photo-Association

Atoms
In this work, a comprehensive theoretical investigation is carried out to explore the electronic and spectroscopic properties of selected diatomic molecular ions MgRb+ and SrRb+. Using high-level ab initio calculations based on a pseudopotential approach,

Modeling optical formation of ultracold NaK_{2} ground-state molecules

Physical Review Research
We study the rovibronic transitions in NaK_{2} between its electronic ground state 1^{2}A^{′} and its second excited state 3^{2}A^{′}, to identify possible pathways for the creation of ultracold ground-state triatomic molecules. Our methodology relies on

Photoassociation of cold metastable helium atoms [PDF]

, 2001
During the last decades the study of cold atoms has grown in a great measure. Research in this field has been made possible due to the development of laser cooling and trapping techniques.

Saturation effects in photoassociation spectroscopy of strontium-86

, 2006
This work describes intensity saturation of photoassociative transitions of 86Sr at the quantum mechanical unitarity limit. The saturation behavior, which results in a roll-over of the photoassociation rate for intensities greater than the saturation ...

A pump-probe study of the photoassociation of cold rubidium molecules.

, 2009
The dynamics of the excited state during the photoassociation of cold molecules from cold rubidium atoms is studied in a series of pump-probe experiments. Dipole transitions similar to those of the atoms are observed in the molecular signal.

Robust control of photoassociation of slow O + H collision

, 2017
We show that robust laser pulses can be obtained by a sampling-based method to achieve a desired photoassociation probability when uncertainties in potential curves and laser amplitudes are considered.

Effects of rotation in the laser-pulse photoassociation in a thermal gas of atoms

, 2013
Photoassociation is a possible route for the formation of chemical bonds. In this process, the binding of colliding atoms can be induced by means of a laser field.

Photoassociation in a quantum degenerate gas of lithium-7

, 2005
An experiment studying the effects of photoassociation in a quantum degenerate gas of 7Li bosons has been performed in a permanent magnet trap. A saturation in the one-photon photoassociation rate and a shift in the resonance due to the applied light ...
