Giant formation rates of ultracold molecules via Feshbach Optimized Photoassociation

, 2008
Ultracold molecules offer a broad variety of applications, ranging from metrology to quantum computing. However, forming "real" ultracold molecules, {\it i.e.} in deeply bound levels, is a very difficult proposition. Here, we show how photoassociation in

Two-photon pathway to ultracold ground state molecules of 23Na40K

New Journal of Physics, 2015
We report on high-resolution spectroscopy of ultracold fermionic ^23 Na ^40 K Feshbach molecules, and identify a two-photon pathway to the rovibrational singlet ground state via a resonantly mixed B ^1 Π ∼ c ^3 Σ ^+ intermediate state.

Electronic structure and photoassociation scheme of ultracold (MgK+) molecular ions

Journal of Physics B: Atomic, Molecular and Optical Physics, 2019
The adiabatic potential energy curves, permanent and transition dipole moments (TDMs) of the highly-excited states of the MgK+ molecular ion have been computed as a function of the inter-nuclear distance R.

Ultracold long-range van der Waals Rydberg trimers

Communications Physics
Rydberg molecules are an essential ingredient of cold molecular sciences. Due to the richness of interactions between Rydberg atoms and neutral atoms, new kinds of Rydberg molecules and binding mechanisms are still to be discovered.

Bifurcations and bistability in cavity assisted photoassociation of Bose-Einstein condensed molecules

, 2007
We study the photo-association of Bose-Einstein condensed atoms into molecules using an optical cavity field. The driven cavity field introduces a new dynamical degree of freedom into the photoassociation process, whose role in determining the stationary

Extensive high-resolution photoassociation spectra and perturbation analysis of the 2(0−) long-range state of ultracold RbCs molecules

Physical Review A, 2019
We report high-resolution photoassociation (PA) spectra of RbCs in the 2(0−) long-range state. Transitions to more than 50 vibrational levels were recorded with the largest binding energy being 507.5 cm−1.

Cavity optomechanical quantum memory for twisted photons using a ring Bose-Einstein condensate

Physical Review Research
We theoretically propose a photonic orbital angular momentum quantum memory, currently of great interest from the perspective of quantum networks, based on a ring-trapped Bose-Einstein condensate interacting with Laguerre-Gaussian beams.

Formation of ultracold SrYb molecules in an optical lattice by photoassociation spectroscopy: theoretical prospects

, 2011
State-of-the-art {\em ab initio} techniques have been applied to compute the potential energy curves for the SrYb molecule in the Born-Oppenheimer approximation for the ground state and first fifteen excited singlet and triplet states within the coupled ...

Modeling optical formation of ultracold NaK_{2} ground-state molecules

Physical Review Research
We study the rovibronic transitions in NaK_{2} between its electronic ground state 1^{2}A^{′} and its second excited state 3^{2}A^{′}, to identify possible pathways for the creation of ultracold ground-state triatomic molecules. Our methodology relies on
