One-dimensional magneto-optical compression of a cold CaF molecular beam

open access: yesNew Journal of Physics, 2017
We demonstrate the one-dimensional, transverse magneto-optical compression of a cold beam of calcium monofluoride (CaF). By continually alternating the magnetic field direction and laser polarizations of the magneto-optical trap (RF MOT), a photon ...

Spin noise spectroscopy to probe quantum states of ultracold fermionic atomic gases [PDF]

open access: yes, 2006
Ultracold alkali atoms provide experimentally accessible model systems for probing quantum states that manifest themselves at the macroscopic scale. Recent experimental realizations of superfluidity in dilute gases of ultracold fermionic (half-integer ...

Impact of non-unitary spin squeezing on atomic clock performance

open access: yesNew Journal of Physics, 2018
Spin squeezing is a form of entanglement that can improve the stability of quantum sensors operating with multiple particles, by inducing inter-particle correlations that redistribute the quantum projection noise.

Determination of CaOH and CaOCH3 vibrational branching ratios for direct laser cooling and trapping

open access: yesNew Journal of Physics, 2019
Alkaline earth monoalkoxide free radicals (MORs) have molecular properties conducive to direct laser cooling to sub-millikelvin temperatures. Using dispersed laser induced fluorescence measurements from a pulsed supersonic molecular beam source we ...

Phase dependent loading of Bloch bands and Quantum simulation of relativistic wave equation predictions with ultracold atoms in variably shaped optical lattice potentials

open access: yes, 2015
The dispersion relation of ultracold atoms in variably shaped optical lattices can be tuned to resemble that of a relativistic particle, i.e. be linear instead of the usual nonrelativistic quadratic dispersion relation of a free atom.

Suppressing dipolar relaxation in thin layers of dysprosium atoms

open access: yesNature Communications
The dipolar interaction can be attractive or repulsive, depending on the position and orientation of the dipoles. Constraining atoms to a plane with their magnetic moment aligned perpendicularly leads to a largely side-by-side repulsion and generates a ...

The Peierls substitution in an engineered lattice potential

open access: yes, 2012
Artificial gauge fields open new possibilities to realize quantum many-body systems with ultracold atoms, by engineering Hamiltonians usually associated with electronic systems.

Ultracold Rydberg Atoms [PDF]

open access: yes, 2011
This thesis presents a new experimental facility that has been developed in the course of the PhD of the author together with the experimental measurements of the dipole moments for transitions between 5P3/2 and nD5/2 states in Rb atoms, where 20 ≤ n ≤ 48.

Laser based accelerator for ultracold atoms [PDF]

open access: yesOptics Letters, 2012
We present first results on our implementation of a laser based accelerator for ultracold atoms. Atoms cooled to a temperature of 420 nK are confined and accelerated by means of laser tweezer beams and the atomic scattering is directly observed in laser absorption imaging. The optical collider has been characterized using Rb87 atoms in the |F=2,mF=2>
