Linear and non-linear coherent coupling in a Bell-Bloom magnetometer
R. Gartman, V. Guarrera, G. Bevilacqua +1
Spin-exchange collisions in hot vapours are generally regarded as a decoherence mechanism. In contrast, we show that linear and non-linear spin-exchange coupling can lead to the ge…
Parametric amplification and noise-squeezing in room temperature atomic vapours
V. Guarrera, R. Gartman, G. Bevilacqua +2
We report on the use of parametric excitation to coherently manipulate the collective spin state of an atomic vapour at room temperature. Signatures of the parametric excitation ar…
Effect of interactions on the localization of a Bose-Einstein condensate in a quasi-periodic lattice
J. E. Lye, L. Fallani, C. Fort +4
The transport properties of a Bose-Einstein condensate in a 1D incommensurate bichromatic lattice are investigated both theoretically and experimentally. We observe a blockage of t…
Towards a Bose-Glass of ultracold atoms in a disordered crystal of light
L. Fallani, J. E. Lye, V. Guarrera +2
Starting from one-dimensional Mott Insulators, we use a bichromatic optical lattice to add controlled disorder to an ideal optical crystal where bosonic atoms are pinned by repulsi…
