Single-atom-resolved probing of lattice gases in momentum space
Hugo Cayla, Cécile Carcy, Quentin Bouton +4
Measuring the full distribution of individual particles is of fundamental importance to characterize many-body quantum systems through correlation functions at any order. Here we d…
Momentum-resolved observation of thermal and quantum depletion in an interacting Bose gas
R. Chang, Q. Bouton, H. Cayla +4
We report on the single-atom-resolved measurement of the distribution of momenta in a weakly interacting Bose gas after a 330 ms time-of-flight. We investigate it for var…
Characterization of a detector chain using a FPGA-based Time-to-Digital Converter to reconstruct the three-dimensional coordinates of single particles at high flux
F. Nogrette, D. Heurteau, R. Chang +4
We report on the development of a novel FPGA-based Time-to-Digital Converter and its implementation in a detection chain that records the coordinates of single particles along thre…
Fast production of Bose-Einstein condensates of metastable Helium
Q. Bouton, R. Chang, A. L. Hoendervanger +4
We report on the Bose-Einstein condensation of metastable Helium-4 atoms using a hybrid approach, consisting of a magnetic quadrupole and a crossed optical dipole trap. In our setu…
Three-dimensional laser cooling at the Doppler limit
Rockson Chang, Lynn Hoendervanger, Quentin Bouton +6
Many predictions of Doppler cooling theory of two-level atoms have never been verified in a three-dimensional geometry, including the celebrated minimum achievable temperature $\hb…
Macroscopic coherence between quantum condensates formed at different times
Alex Hayat, Christoph Lange, Lee A. Rozema +8
We demonstrate macroscopic coherence between quantum condensates generated at different times, separated by more than the particle dephasing time. This is possible due to the dress…
Observing the Onset of Effective Mass
Rockson Chang, Shreyas Potnis, Ramon Ramos +6
The response of a particle in a periodic potential to an applied force is commonly described by an effective mass which accounts for the detailed interaction between the particle a…
Observation of Transient Momentum-Space Interference During Scattering of a Condensate From an Optical Barrier
Rockson Chang, Shreyas Potnis, Christopher W. Ellenor +3
Scattering theory traditionally deals with the asymptotic behaviour of a system far removed from the actual scattering event. Here we present an experimental study of the one-dimen…
