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.

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.

Tuning interactions between static-field-shielded polar molecules with microwaves

Physical Review Research
The ability to tune interparticle interactions is one of the main advantages of using ultracold quantum gases for quantum simulation of many-body physics.

Ultracold High-Spin Σ-State Polar Molecules for New Physics Searches

Physical Review X
We propose high-spin Σ-state polar molecules assembled from ultracold atoms to probe charge-parity-violating physics beyond the standard model. We identify YbCr as a prime candidate to search for the electric dipole moment of the electron.

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.

QUANTUM REFLECTION AND THE INTERACTIONS OF ULTRACOLD ATOMS WITH SURFACES AND NANOSTRUCTURES

Momento, 2011
Quantum reflection refers to the reflection of particles by attractive long-range potentials in nonclassical regions of coordinate space without reaching a classical turning point.

Ultracold collisions of molecules

, 2017
This paper deals with the theory of collisions between two ultracold particles with a special focus on molecules. It describes the general features of the scattering theory of two particles with internal structure, using a time-independent quantum formalism.
