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…

Comparative investigation of 39K and 40K trap loss rates: alternative loss channel at low light intensities

G. Modugno, G. Roati, M. Inguscio +4

We report a comparative investigation of trap loss rates in a magneto-optical trap for two potassium isotopes, 39K and 40K, as a function of trap light intensity. The isotopes pres…

Dynamic structure factor of a superfluid Fermi gas

Anna Minguzzi, Gabriele Ferrari, Yvan Castin

We describe the excitation spectrum of a two-component neutral Fermi gas in the superfluid phase at finite temperature by deriving a suitable Random-Phase approximation with the te…

Anharmonic parametric excitation in optical lattices

R. Jáuregui, N. Poli, G. Roati +1

We study both experimentally and theoretically the losses induced by parametric excitation in far-off-resonance optical lattices. The atoms confined in a 1D sinusoidal lattice pres…

Slow group velocity and Cherenkov radiation

I. Carusotto, M. Artoni, G. C. La Rocca +1

We theoretically study the effect of ultraslow group velocities on the emission of Vavilov-Cherenkov radiation in a coherently driven medium. We show that in this case the aperture…

Spatial interference of coherent atomic waves by manipulation of the internal quantum state

C. Fort, P. Maddaloni, F. Minardi +2

A trapped 87Rb Bose-Einstein condensate is initially put into a superposition of two internal states. Under the effect of gravity and by means of a second transition, we prepare tw…
