Coherent Manipulation of Orbital Feshbach Molecules of Two-Electron Atoms

Physical Review X, 2019
Ultracold molecules have experienced increasing attention in recent years. Compared to ultracold atoms, they possess several unique properties that make them perfect candidates for the implementation of new quantum-technological applications in several ...

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.

Trapping of ultracold polar molecules with a Thin Wire Electrostatic Trap

, 2007
We describe the realization of a dc electric-field trap for ultracold polar molecules, the thin-wire electrostatic trap (TWIST). The thin wires that form the electrodes of the TWIST allow us to superimpose the trap onto a magneto-optical trap (MOT).

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.

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.

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

Theoretical Calculation of Ground and Electronically Excited States of MgRb⁺ and SrRb⁺ Molecular Ions: Electronic Structure and Prospects of Photo-Association

Atoms
In this work, a comprehensive theoretical investigation is carried out to explore the electronic and spectroscopic properties of selected diatomic molecular ions MgRb+ and SrRb+. Using high-level ab initio calculations based on a pseudopotential approach,

Boson-Fermion coherence in a spherically symmetric harmonic trap

, 2004
We consider the photoassociation of a low-density gas of quantum-degenerate trapped fermionic atoms into bosonic molecules in a spherically symmetric harmonic potential.

Photoassociative Spectroscopy of Ultracold NaCs

Frontiers in Optics, 2006
We present photoassociation spectroscopy of ultracold NaCs below the cesium D-line. Vibrational progressions are assigned to long range Hund case (c) states based on diabatic potentials with spin-orbit interaction included in a perturbative approach.

Superposition of macroscopic numbers of atoms and molecules

, 2001
We theoretically examine photoassociation of a non-ideal Bose-Einstein condensate, focusing on evidence for a macroscopic superposition of atoms and molecules.
