Atom interferometry using - Raman transitions between and
Jeanne Bernard, Yannick Bidel, Malo Cadoret +6
We report on the experimental demonstration of a horizontal accelerometer based on atom interferometry using counterpropagative Raman transitions between the states …
An optical elevator for precise delivery of cold atoms using an acousto-optical deflector
Francesco Ferri, Arthur La Rooij, Claire Lebouteiller +6
We implement a simple method for fast and precise delivery of ultracold atoms to a microscopic device, i.e. a Fabry-Perot microcavity. By moving a single beam optical dipole trap i…
Effect of trap symmetry and atom-atom interactions on a trapped atom interferometer with internal state labelling
M. Dupont-Nivet, C. I. Westbrook, S. Schwartz
In this paper, we study the dynamics of a trapped atom interferometer with internal state labelling in the presence of interactions. We consider two situations: an atomic clock in…
Contrast and phase-shift of a trapped atom interferometer using a thermal ensemble with internal state labelling
M. Dupont-Nivet, C. I. Westbrook, S. Schwartz
We report a theoretical study of a double-well Ramsey interferometer using internal state labelling. We consider the use of a thermal ensemble of cold atoms rather than a Bose-Eins…
Microwave-stimulated Raman adiabatic passage in a Bose-Einstein condensate on an atom chip
Matthieu Dupont-Nivet, Mathias Casiulis, Théo Laudat +2
We report the achievement of stimulated Raman adiabatic passage (STIRAP) in the microwave frequency range between internal states of a Bose-Einstein condensate (BEC) magnetically t…
Symmetric micro-wave potentials for interferometry with thermal atoms on a chip
M. Ammar, M. Dupont-Nivet, L. Huet +8
A trapped atom interferometer involving state-selective adiabatic potentials with two microwave frequencies on a chip is proposed. We show that this configuration provides a way to…
Magneto-optical Trapping through a Transparent Silicon Carbide Atom Chip
Landry Huet, Mahdi Ammar, Erwan Morvan +5
We demonstrate the possibility of trapping about one hundred million rubidium atoms in a magneto-optical trap with several of the beams passing through a transparent atom chip moun…
