Mesoscopic BCS pairing in the repulsive 1d-Hubbard model

Luigi Amico, Andrea Mastellone, Andreas Osterloh

We study mesoscopic pairing in the one dimensional repulsive Hubbard model and its interplay with the BCS model in the canonical ensemble. The key tool is comparing the Bethe ansat…

The very young planetary nebula LS IV -12 111

L. Cerrigone, G. Umana, C. Trigilio

In the last few years we have started a systematic study aimed at detecting very young Planetary Nebulae (YPNs). The project, based on both radio (multi-frequency and high resoluti…

Reading entanglement in terms of spin configurations in quantum magnets

Andrea Fubini, Tommaso Roscilde, Valerio Tognetti +2

We consider a quantum many-body system made of interacting spins on a lattice, and develop a formalism which allows to extract, out of conventional magnetic observabl…

Simulating galaxy clusters : the ICM and the galaxy populations

Alessio D. Romeo, J. Sommer-Larsen, L. Portinari

Cosmological LambdaCDM TreeSPH simulations of the formation and evolution of galaxy groups and clusters have been performed. The simulations include: star formation, chemical evolu…

Slow Light amplification in a non-inverted gain medium

Filippo Caruso, Ivan Herrera, Saverio Bartalini +1

We investigate the propagation of a coherent probe light pulse through a three-level atomic medium (in the --configuration) in the presence of a pump laser under the conditions…

Opinion dynamics and decision of vote in bipolar political systems

Filippo Caruso, Paolo Castorina

A model of the opinion dynamics underlying the political decision is proposed. The analysis is restricted to a bipolar scheme with a possible third political area. The interaction…
