Universal Borromean Binding in Spin-Orbit-Coupled Ultracold Fermi Gases

Physical Review X, 2014
Borromean rings and Borromean binding, a class of intriguing phenomena as three objects are linked (bound) together while any two of them are unlinked (unbound), widely exist in nature and have been found in systems of biology, chemistry, and physics ...

Interaction between polar molecules subject to a far-off-resonant optical field: Entangled dipoles up- or down-holding each other

, 2011
We show that the electric dipole-dipole interaction between a pair of polar molecules undergoes an all-out transformation when superimposed by a far-off resonant optical field. The combined interaction potential becomes tunable by variation of wavelength,

Ultracold mixtures of metastable He and Rb: scattering lengths from ab initio calculations and thermalization measurements

, 2014
We have investigated the ultracold interspecies scattering properties of metastable triplet He and Rb. We performed state-of-the-art ab initio calculations of the relevant interaction potential, and measured the interspecies elastic cross section for an ...

Ultracold physics and cold chemistry

, 2022
This thesis studies single ions inside a radio-frequency trap interacting with ultracold neutral particles. During a collision, the ion can gain energy from the time-dependent trapping field, which limits the attainable collision energies. We mitigate this effects by using Yb+ ions and Li atoms, the elements with the largest ion-to-atom mass ratio that

State-to-state chemistry with ultracold neutral Rb atoms

, 2020
In this thesis, I report on experiments on the detection and the production of molecules in an ultracold atomic gas. These experiments can be divided into two main parts. The first part is about state-to-state experiments where chemical reaction products are detected in a quantum state resolved way. The second part is about Rydberg molecules.
