Dynamically probing ultracold lattice gases via Rydberg molecules

New Journal of Physics, 2015
We show that the excitation of long-range Rydberg molecules in a three-dimensional optical lattice can be used as a position- and time-sensitive probe for doubly occupied sites in the system.

Ultracold interactions between ions and polar molecules

Physical Review Research
We propose a platform for observing and controlling the interactions between atomic ions and a quantum gas of polar molecules in the ultracold regime.

A Zeeman slower for diatomic molecules

New Journal of Physics, 2018
We present a novel slowing scheme for beams of laser-coolable diatomic molecules reminiscent of Zeeman slowing of atomic beams. The scheme results in efficient compression of the one-dimensional velocity distribution to velocities trappable by magnetic ...

Tuning ultracold collisions of excited rotational dipolar molecules

New Journal of Physics, 2015
We investigate the ultracold collisions of rotationally excited dipolar molecules in free-space, taking the hetero-nuclear bi-alkali molecule of KRb as an example.

Formation of ultracold 39KCs Feshbach molecules

We report the creation of an ultracold gas of bosonic $^{39}$K$^{133}$Cs molecules. We first demonstrate a cooling strategy relying on sympathetic cooling of $^{133}$Cs to produce an ultracold mixture. From this mixture, weakly bound molecules are formed

Formation of Ultracold Molecules

, 2016
Advances in our ability to slow down and cool atoms and molecules to ultracold temperatures have paved the way to a revolution in basic research on molecules. Ultracold molecules are sensitive of very weak interactions, even when separated by large distances, which allow studies of the effect of those interactions on the behavior of molecules.

Observation of a Halo Trimer in an Ultracold Bose-Fermi Mixture

Physical Review X
The quantum mechanics of three interacting particles gives rise to fundamental and universal phenomena, such as the staircase of Efimov trimers predicted in the context of nuclear physics and observed in ultracold gases.

Efficient conversion of ultracold Feshbach-resonance-related polar molecules into ultracold ground state (X

, 2004
It is proposed that bound states of ultracold heteronuclear alkali dimer molecules derived from Feshbach resonances can be efficiently converted into true ground state ultracold molecules (X $^{1}{\Sigma}^{ +}$ v = 0, J = 0) by a stimulated Raman ...

Creation of ultracold RbCs molecules [PDF]

, 2014
This thesis reports the investigation of the scattering properties of a mixture of Rb and Cs and the formation of ultracold Feshbach molecules. The production of Feshbach molecules is a crucial step towards the production of ultracold polar molecules ...
