Magnetic dipolar interaction in an atomic Bose Einstein condensate interferometer (2008)
Fattori, M., Roati, G., Deissler, B., D'Errico, C., Zaccanti, M., Jona-Lasinio, M., ...
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-wave interaction to...
Anderson localization of a non-interacting Bose-Einstein condensate (2008)
Roati, G., D'Errico, C., Fallani, L., Fattori, M., Fort, C., Zaccanti, M., ...
One of the most intriguing phenomena in physics is the localization of waves in disordered media. This phenomenon was originally predicted by Anderson, fifty years ago, in the context of transport of...
Simoni, A., Zaccanti, M., D'Errico, C., Fattori, M., Roati, G., Inguscio, M., ...
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 observations of resonance...
Feshbach resonances in ultracold K(39) (2007)
D'Errico, C., Zaccanti, M., Fattori, M., Roati, G., Inguscio, M., Modugno, G., ...
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-field resonance...
Fröhlich, B., Lahaye, T., Kaltenhäuser, B., Kübler, H., Müller, S., Koch, T., ...
We report on a scheme to improve the pointing stability of the first order beam diffracted by an acousto-optic modulator (AOM). Due to thermal effects inside the crystal, the angular position of the...
Spinor condensates with a laser-induced quadratic Zeeman effect (2006)
Santos, L., Fattori, M., Stuhler, J., Pfau, T.
We show that an effective quadratic Zeeman effect can be generated in $^{52}$Cr by proper laser configurations, and in particular by the dipole trap itself. The induced quadratic Zeeman effect leads...
Observation of dipole-dipole interaction in a degenerate quantum gas (2006)
Stuhler, J., Griesmaier, A., Koch, T., Fattori, M., Pfau, T., Giovanazzi, S., ...
We have investigated the expansion of a Bose-Einstein condensate (BEC) of strongly magnetic chromium atoms. The long-range and anisotropic magnetic dipole-dipole interaction leads to an anisotropic...
Damagnetization cooling of a gas (2006)
Fattori, M., Koch, T., Goetz, S., Griesmaier, A., Hensler, S., Stuhler, J., ...
We demonstrate demagnetization cooling of a gas of ultracold $^{52}$Cr atoms. Demagnetization is driven by inelastic dipolar collisions which couple the motional degrees of freedom to the spin...
Expansion dynamics of a dipolar Bose-Einstein condensate (2006)
Giovanazzi, S., Pedri, P., Santos, L., Griesmaier, A., Fattori, M., Koch, T., ...
Our recent measurements on the expansion of a chromium dipolar condensate after release from an optical trapping potential are in good agreement with an exact solution of the hydrodynamic equations...
Bertoldi, A., Lamporesi, G., Cacciapuoti, L., De Angelis, M., Fattori, M., Petelski, T., ...
We developed a gravity-gradiometer based on atom interferometry for the determination of the Newtonian gravitational constant \textit{G}. The apparatus, combining a Rb fountain, Raman interferometry...

Effect of polyamine depletion on caspase activation: a study with spermine synthase-deficient cells.
Stefanelli, C, Pignatti, C, Tantini, B, Fattori, M, Stanic, I, Mackintosh, C A, ...
Activation of the caspase proteases represents a central point in apoptosis. The requirement for spermine for the processes leading to caspase activation has been studied in transformed embryonic...
