Structure and interactions of atoms and diatomic molecules: from ultracold gases to doped solids
Maxence Lepers
This is the manuscript of my "Habilitation à diriger des recherches", where I present the research work that I have done after my PhD, defended in 2009. The manuscript is divided i…
Determination of the ground state polarizability of Dy near 530 nm
Alexandre Journeaux, Maxime Lecomte, Julie Veschambre +3
Open-shell lanthanide atoms, and dysprosium in particular, combine a large ground-state angular momentum with dense electronic spectra, making their dynamical polarizability strong…
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…
