  2. •The multiband Hubbard Model and the role of the Hund's coupling: Mott transitions and Superconductivity.




Roser Valentì (University of Frankfurt)


  1. • Organic charge-transfer salts: Spin liquids, charge orders and ferroelectricity.




Rosario Fazio and co-workers  (Scuola Normale Superiore di Pisa)


  1. •Investigation of quantum effects in hybrid systems, Andreev reflection in graphene nanoribbons, Josephson effect in the presence of an excitonic superfluid.





Fabio Beltram, Vittorio Pellegrini, Alessandro Tredicucci  (CNR-NEST, Pisa)


  1. •Investigation of few electron doped quantum dots integrated in photonic crystals. The possibility to control the interaction between the photonic mode of a cavity and the QD electronic excitations and to spectrally tune the two resonances allows to selectively modify the exciton/photon coupling and to possibly enhance the optical response of a single quantum dot.


  1. PRIN Project, A controlled-nanofabrication strategy for the optical manipulation of few-electron states in photonic-cavity                   quantum-dot devices, financed by the Italian Ministry of University and Research.



  1. •Design and simulation of semiconductor-based quantum-cascade lasers [R.C. Iotti and F. Rossi, Phys. Rev. Lett. 87, 146603 (2001)], both in the mid- and in the far-infrared spectral region. This activity has led to the design and fabrication of the first Terahertz laser [R. Koehler et al., Nature 417, 156 (2002)].
