Observation of an Efimov spectrum in an atomic system
M. Zaccanti, B. Deissler, C. D'Errico +6
In 1970 V. Efimov predicted a puzzling quantum-mechanical effect that is still of great interest today. He found that three particles subjected to a resonant pairwise interaction c…
Magnetic dipolar interaction in an atomic Bose Einstein condensate interferometer
M. Fattori, G. Roati, B. Deissler +6
We study the role played by the magnetic dipole interaction in an atomic interferometer based on an alkali Bose-Einstein condensate with tunable scattering length. We tune the s-wa…
Accurate near-threshold model for ultracold KRb dimers from interisotope Feshbach spectroscopy
A. Simoni, M. Zaccanti, C. D'Errico +4
We investigate magnetic Feshbach resonances in two different ultracold K-Rb mixtures. Information on the K(39)-Rb(87) isotopic pair is combined with novel and pre-existing observat…
Atom interferometry with a weakly-interacting Bose Einstein condensate
Marco Fattori, Chiara D'Errico, Giacomo Roati +5
We demonstrate the operation of an atom interferometer based on a weakly interacting Bose-Einstein condensate. We strongly reduce the interaction induced decoherence that usually l…
Feshbach resonances in ultracold K(39)
C. D'Errico, M. Zaccanti, M. Fattori +4
We discover several magnetic Feshbach resonances in collisions of ultracold K(39) atoms, by studying atom losses and molecule formation. Accurate determination of the magnetic-fiel…
39-K Bose-Einstein condensate with tunable interactions
G. Roati, M. Zaccanti, C. D'Errico +5
We produce a Bose-Einstein condensate of 39-K atoms. Condensation of this species with naturally small and negative scattering length is achieved by a combination of sympathetic co…
