Feshbach resonances in potassium Bose-Bose mixtures
L. Tanzi, C. R. Cabrera, J. Sanz +3
We present a detailed study of the scattering properties of ultracold mixtures of bosonic potassium atoms. We locate 20 previously unobserved Feshbach resonances in isotopic 39K-41…
Direct cooling in an optical lattice by amplitude modulation
M. Arnal, V. Brunaud, G. Chatelain +5
We report on a generic cooling technique for atoms trapped in optical lattices. It consists in modulating the lattice depth with a proper frequency sweeping. This filtering techniq…
Bright soliton to quantum droplet transition in a mixture of Bose-Einstein condensates
P. Cheiney, C. R. Cabrera, J. Sanz +3
Attractive Bose-Einstein condensates can host two types of macroscopic self-bound states of different nature: bright solitons and quantum liquid droplets. Here, we investigate the…
Quantum liquid droplets in a mixture of Bose-Einstein condensates
C. R. Cabrera, L. Tanzi, J. Sanz +4
Quantum droplets are small clusters of atoms self-bound by the balance of attractive and repulsive forces. Here we report on the observation of a novel type of droplets, solely sta…
Band gap structures for matter waves
F. Damon, G. Condon, P. Cheiney +4
Spatial gaps correspond to the projection in position space of the gaps of a periodic structure whose envelope varies spatially. They can be easily generated in cold atomic physics…
Realization of tunnel barriers for matter waves using spatial gaps
Pierrick Cheiney, François Damon, Gabriel Condon +2
We experimentally demonstrate the trapping of a propagating Bose-Einstein Condensate in a Bragg cavity produced by an attractive optical lattice with a smooth envelope. As a conseq…
Matter wave scattering on an amplitude-modulated optical lattice
Pierrick Cheiney, Charlotte Fabre, François Vermersch +4
We experimentally study the scattering of guided matter waves on an amplitude-modulated optical lattice. We observe different types of frequency-dependent dips in the asymptotic ou…
Realization of a distributed Bragg reflector for propagating guided matter waves
Charlotte M. Fabre, Pierrick Cheiney, Giovanni Luca Gattobigio +5
We report on the experimental realization of a Bragg reflector for guided matter waves. A Bose-Einstein condensate with controlled velocity distribution impinges onto an attractive…
Guided atom laser: transverse mode quality and longitudinal momentum distribution
François Vermersch, Charlotte Fabre, Pierrick Cheiney +3
We analyze the outcoupling of a matter wave into a guide by a time-dependent spilling of the atoms from an initially trapped Bose-Einstein condensate. This process yields intrinsic…
Zeeman slowers made simple with permanent magnets in a Halbach configuration
P. Cheiney, O. Carraz, D. Bartoszek-Bober +7
We describe a simple Zeeman slower design using permanent magnets. Contrary to common wire-wound setups no electric power and water cooling are required. In addition, the whole sys…
