Self-induced density modulations in the free expansion of Bose-Einstein condensates
L. Salasnich, N. Manini, F. Bonelli +2
We simulate numerically the free expansion of a repulsive Bose-Einstein condensate with an initially Gaussian density profile. We find a self-similar expansion only for weak inter-…

Thermal Effects in Photoemission and Electron-Phonon Couplings of Fullerene
Andrea Bordoni, Nicola Manini
We show that thermal effects play a relevant role in the determination of the electron-phonon couplings based on the intensity of the phonon-shakeup peaks in photoemission spectra.…

Berry Phase and the Symmetry of the Vibronic Ground State in Dynamical Jahn-Teller Systems
Nicola Manini, Paolo De Los Rios
Due to the frequent presence of a Berry phase, in most cases of dynamical Jahn-Teller systems the symmetry of the ground state is the same as that of the electronic state. However,…
