Revisiting the luminescence properties of Pr3+: YAG within the framework of an extended approach of Judd-Ofelt theory
Maxence Lepers, G. Hovhannesyan, Y. Guyot +2
We show in this article the improvements which can be obtained in the description of the luminescence properties of Pr3+ doped materials by using an extension of the Judd-Ofelt 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…
