Raman Sideband Cooling of Molecules in an Optical Tweezer Array to the 3D Motional Ground State
Physical Review XUltracold polar molecules are promising for quantum information processing and searches for physics beyond the standard model. Laser cooling to ultracold temperatures is an established technique for trapped diatomic and triatomic molecules.

Manipulating scattering of ultracold atoms with light-induced dissipation
Frontiers in Physics, 2013 Recently it has been shown that pairs of atoms can form metastable bonds due to non-conservative forces induced by dissipation [Lemeshko&Weimer, Nature Comm. textbf{4}, 2230 (2013)].

Quantum fluctuations of ultracold atom–molecule mixtures [PDF]
physica status solidi (b), 2005 AbstractWe investigate the evolution of quantum coherence in an ultracold mixture of fermionic atoms and bosonic dimer molecules. Interactions are experimentally controlled via tuning the external magnetic field. Consequently, the fermionic atoms and their bosonic counterparts can be driven to a behavior resembling the usual BCS to BEC crossover.

Dynamical effects and disorder in ultracold bosonic matter [PDF]
, 2013 In this thesis, various aspects on the theoretical description of ultracold bosonic atoms in optical lattices are investigated. After giving a brief introduction to the fundamental concepts of BECs, atomic physics, interatomic interactions and ...

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 ...

Formation of ultracold 39KCs Feshbach molecules [PDF]
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.

Physical Review ResearchWe theoretically investigate the collisions between ultracold polar molecules in the presence of two lasers ensuring a Raman resonant transition on individual molecules to suppress photon scattering, taking the example of bosonic ^{23}Na^{39}K molecules.
