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…

Optical formation of ultracold NaK ground state molecules

Baraa Shammout, Leon Karpa, Silke Ospelkaus +2

We study the rovibronic transitions in NaK between its electronic ground state and its second excited state , to identify possible pathways for the creation of u…

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…

Demonstration of deuterium's enhanced sensitivity to symmetry violations governed by the Standard-Model Extension

Amit Nanda, Daniel Comparat, Olivier Dulieu +5

We have performed hyperfine spectroscopy of two transitions in ground-state deuterium and searched for violations of CPT and Lorentz symmetry that would manifest as sidereal variat…
