Long-wavelength optical lattices from optical beatnotes: theory and applications
Tommaso Petrucciani, Andrea Santoni, Chiara Mazzinghi +4
We present a theoretical analysis of Beat-Note Superlattices (BNSLs), a recently demonstrated technique for generating periodic trapping potentials for ultracold atomic clouds, wit…
Dynamical formation of multiple quantum droplets in a Bose-Bose mixture
L. Cavicchioli, C. Fort, F. Ancilotto +3
We report on the formation of multiple quantum droplets in a heteronuclear K-Rb mixture released in an optical waveguide. By a sudden change of the interspecies inter…
Effective expression of the Lee-Huang-Yang energy functional for heteronuclear mixtures
F. Minardi, F. Ancilotto, A. Burchianti +3
We consider a homogeneous heteronuclear Bose mixture with contact interactions at the mean-field collapse, i.e. with interspecies attraction equal to the mean geometrical intraspec…
Collision of impurities with Bose-Einstein condensates
F. Lingua, L. Lepori, F. Minardi +2
Quantum dynamics of impurities in a bath of bosons is a long-standing problem of solid-state, plasma, and atomic physics. Recent experimental and theoretical investigations with ul…
Thermometry of bosonic mixtures in Optical Lattices via Demixing
F. Lingua, B. Capogrosso-Sansone, F. Minardi +1
Motivated by recent experiments and theoretical investigations on binary mixtures, we investigate the miscible-immiscible transition at finite temperature by means of Quantum Monte…
Bose-Einstein Condensates in a 1D Optical Lattice
S. Burger, F. S. Cataliotti, F. Ferlaino +4
We give an overview on current experiments on Bose-Einstein condensation (BEC) in a one-dimensional (1D) optical lattice. We introduce measurements of ground state, tunnelling and…
Josephson Junction Arrays with Bose-Einstein Condensates
F. S. Cataliotti, S. Burger, C. Fort +5
We report on the direct observation of an oscillating atomic current in a one-dimensional array of Josephson junctions realized with an atomic Bose-Einstein condensate. The array i…
Quasi 2D Bose-Einstein condensation in an optical lattice
S. Burger, F. S. Cataliotti, C. Fort +3
We study the phase transition of a gas of Rb atoms to quantum degeneracy in the combined potential of a harmonically confining magnetic trap and the periodic potential of an optica…
Expansion of a coherent array of Bose-Einstein condensates
P. Pedri, L. Pitaevskii, S. Stringari +6
We investigate the properties of a coherent array containing about 200 Bose-Einstein condensates produced in a far detuned 1D optical lattice. The density profile of the gas, image…
Time-domain atom interferometry across the threshold for Bose-Einstein condensation
F. Minardi, C. Fort, P. Maddaloni +2
We have performed time-domain interferometry experiments with matter waves trapped in an harmonic potential above and below the Bose-Einstein phase transition. We interrogate the a…
Superfluid and Dissipative Dynamics of a Bose-Einstein Condensate in a Periodic Optical Potential
S. Burger, F. S. Cataliotti, C. Fort +4
We create Bose-Einstein condensates of 87-rubidium in a static magnetic trap with a superimposed blue-detuned 1D optical lattice. By displacing the magnetic trap center we are able…
Dynamics of two colliding Bose-Einstein condensates in an elongated magneto-static trap
M. Modugno, F. Dalfovo, C. Fort +2
We study the dynamics of two interacting Bose-Einstein condensates, by numerically solving two coupled Gross-Pitaevskii equations at zero temperature. We consider the case of a sud…
Collective oscillations of two colliding Bose-Einstein condensates
P. Maddaloni, M. Modugno, C. Fort +2
Two 87Rb condensates (F=2, m_f=2 and m_f=1) are produced in highly displaced harmonic traps and the collective dynamical behaviour is investigated. The mutual interaction between t…
