Anomalous decoherence rate of macroscopic superpositions in Bose Josephson junctions (2009)
Ferrini, G., Spehner, D., Minguzzi, A., Hekking, F. W. J.
Macroscopic superpositions of coherent states have been predicted to be generated dynamically in a Bose Josephson junction realized by an ultracold Bose gas in a double well potential. We consider...
Montagnese, M., Pagliara, S., Conte, S. Dal, Galimberti, G., Ferrini, G., Parmigiani, F.

Ultrafast laser pulses to detect and generate fast thermo-mechanical transients in matter (2009)
Giannetti, C., Banfi, F., Nardi, D., Ferrini, G., Parmigiani, F.
The use of femtosecond laser pulses to impulsively excite thermal and mechanical transients in matter has led, in the last years, to the development of picosecond acoustics. Recently, the pump-probe...
