Observing the intrinsic linewidth of a quantum-cascade laser: beyond the Schawlow-Townes limit

S. Bartalini, S. Borri, P. Cancio +6

A comprehensive investigation of the frequency-noise spectral density of a free-running mid-infrared quantum-cascade laser is presented for the first time. It provides direct evide…

Saturated-absorption cavity ring-down spectroscopy

G. Giusfredi, S. Bartalini, S. Borri +4

We report on a novel approach to cavity-ring-down spectroscopy with the sample gas in saturated-absorption regime. This technique allows to decouple and simultaneously retrieve emp…

Entropy exchange in a mixture of ultracold atoms

J. Catani, G. Barontini, G. Lamporesi +5

We investigate experimentally the entropy transfer between two distinguishable atomic quantum gases at ultralow temperatures. Exploiting a species-selective trapping potential, we…

Three Resonant Ultra-Cold Bosons: Off-Resonance Effects

Mattia Jona-Lasinio, Ludovic Pricoupenko

We solve a finite range two-channel model for three resonant identical bosons. The model provides a minimal description of the various magnetic Feshbach resonances in single specie…

Excitations of Bose-Einstein condensates in a one-dimensional periodic potential

N. Fabbri, D. Clément, L. Fallani +4

We report on the experimental investigation of the response of a three-dimensional Bose-Einstein condensate (BEC) in the presence of a one-dimensional (1D) optical lattice. By mean…

Exponential localization in one-dimensional quasiperiodic optical lattices

Michele Modugno

We investigate the localization properties of a one-dimensional bichromatic optical lattice in the tight binding regime, by discussing how exponentially localized states emerge upo…
