Rotational laser spectroscopy of the transition of molecule in a supersonic beam: As good as it gets
David Rodríguez Fernández, Manuel Alejandro Lefrán Torres, Jaime Javier Borges Márquez +6
High-resolution laser spectroscopy of the , , and isotopologues has been performed in a supersonic molecu…
Quantum study of ultracold atom-ion excitation exchange
Tibor Jónás, Romain Vexiau, Nadia Bouloufa-Maafa +3
The quantum dynamics of ultracold collisions between rubidium atoms and excited metastable strontium ions is treated in the laboratory frame, enlightening the importance of the cou…
An Alternate Pathway for H Formation in the Early Universe: A physical process to account for the presence and coevolution of the luminous galaxies and supermassive black holes at the high redshifts
Amrendra Pandey, Olivier Dulieu, Nadia Bouloufa-Maafa
Molecular hydrogen (H) and hydrogen deuteride (HD) are key coolants in primordial gas and regulate the formation of the first stars and proto-galaxies. Recent results from the…
Two-photon-assisted collisions in ultracold gases of polar molecules II : Optical shielding of ultracold polar molecular collisions
Gohar Hovhannesyan, Charbel Karam, Romain Vexiau +4
We theoretically investigate the collisions between ultracold polar molecules in the presence of two lasers ensuring a Raman resonant transition on individual molecules to suppress…
Two-photon-assisted collisions in ultracold gases of polar molecules
Charbel Karam, Gohar Hovhannesyan, Romain Vexiau +3
We present a theoretical formalism to treat the ultracold dynamics of a pair of colliding polar molecules submitted to two laser fields. We express the dressed Hamiltonian includin…
