Laser-intensity dependence of photoassociation in ultracold metastable helium [PDF]
, 2009 Photoassociation of spin-polarized metastable helium to the three lowest rovibrational levels of the J=1, 0u+ state asymptoting to 2s 3S1+2p 3P0 is studied using a second-order perturbative treatment of the line shifts valid for low laser intensities ...

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.

Formation of ultracold molecules via photoassociation with blue detuned laser light
, 2001 We propose a new possibility to form ultracold molecules, via photoassociation of a pair of cold atoms into vibrational levels of the external well of an excited electronic state located at intermediate interatomic distance ($\approx 20$ Bohr radii), and

Nonlinear photoassociation through exotic orbits
, 2021 We investigate the effects of a particular kind of orbits, which we call exotic orbits, on the process of classical molecular photoassociation. As a starting model system, we consider the process described by the Morse potential with a time-dependent ...

Cavity optomechanical quantum memory for twisted photons using a ring Bose-Einstein condensate
Physical Review ResearchWe 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.
