Investigating the Selective Control of Photoassociation of Yb2

open access: yesInternational Journal of Optics, 2021
The selective control of photoassociation of Yb2 is investigated in theory. Based on ab initio to rationalize Franck–Condon filtering, the optimal target states of photoassociation have been obtained.

Modeling Photoassociative Spectra of Ultracold NaK + K. [PDF]

open access: yesJ 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.

Exploring the vibrational series of pure trilobite Rydberg molecules [PDF]

open access: yesNature Communications, 2023
In trilobite Rydberg molecules, an atom in the ground state is bound by electron-atom scattering to a Rydberg electron that is in a superposition of high angular momentum states.

Rydberg-State Double-Well Potentials of Van der Waals Molecules [PDF]

open access: yesMolecules
Recent progress in studies of Rydberg double-well electronic energy states of MeNg (Me = 12-group atom, Ng = noble gas atom) van der Waals (vdW) molecules is presented and analysed. The presentation covers approaches in experimental studies as well as ab

Short-range photoassociation of LiRb

open access: yesPhysical Review A, 2016
We have observed short-range photoassociation of LiRb to the two lowest vibrational states of the $d\,^3 $ potential. These $d\,^3 $ molecules then spontaneously decay to vibrational levels of the $a^3\, ^+$ state with generation rates of $\sim10^3$ molecules per second. This is the first observation of many of these $a\,^3 ^+$ levels.

Photoassociation of Spin-Polarized Hydrogen [PDF]

open access: yesPhysical Review Letters, 1999
Using Lyman- $\ensuremath{\alpha}$ spectroscopy we observe photoassociation of spin-polarized hydrogen atoms to bound vibrational levels of the triplet ${a}^{3}{\ensuremath{\Sigma}}_{g}^{+}$ potential. At a density of ${10}^{16}\mathrm{atoms}/{\mathrm{cm}}^{3}$ we directly observe light absorption and fluorescence in the photoassociation process.

Photoassociation Spectroscopy of Laser-Cooled Ytterbium Atoms [PDF]

open access: yesPhysical Review Letters, 2004
We report the photoassociation spectroscopy of laser-cooled ytterbium atoms in an optical trap. We observed more than 90 photoassociation resonances of vibrational levels in the (1)Sigma(+)(u) state, including 80 consecutive series, up to 490 GHz detuning with respect to the atomic resonance.

Nonlinear photoassociation through exotic orbits

open access: yesPhysical Review E, 2021
We investigate the effects of a particular kind of orbits, which we call exotic orbits, on the process of classical molecular photoassociation. As a starting model system, we consider the process described by the Morse potential with a time-dependent perturbation consisting of the interaction of an external laser field with the molecular dipole.

Steering thermal photoassociation of magnesium atoms by two time-delayed femtosecond laser pulses

open access: yesFrontiers in Physics, 2023
By solving the full-dimensional time-dependent Schrödinger equation with the thermal-random-phase wavepacket method, we investigate the photoassociation (PA) process of hot (1000 K) magnesium atoms induced by two time-delayed femtosecond laser pulses ...
