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…
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…
Hyperfine-resolved optical spectroscopy of ultracold RbCs molecules: the metastable state
Arpita Das, Albert Li Tao, Luke M. Fernley +6
Using an ultracold gas of RbCs molecules, we perform hyperfine-resolved spectroscopy of transitions from the vibronic ground state to the lowest rovibrational states…
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…
Associative ionization in a dilute ultracold Li gas probed with a hybrid trap
N. Joshi, Vaibhav Mahendrakar, M. Niranjan +6
The formation of Li and subsequently Li ions, during the excitation of Li atoms to the state in a Li magneto optical trap (MOT), is probed in an ion-at…
