Research outline

The research activity covers the study of Correlated Systems at Low Dimensionality by means of field theoretical and many-body approaches to describe physical systems like high-temperature superconductors, one-dimensional electron systems (chains and spin ladders, Luttinger liquids) and nanostructures. Recently my research activity has been focused on the study of spin transport in mesoscopic systems like nanotubes, ferromagnetic-superconducting hybrid nanostructures and on the quantum phase transitions in models of interacting boson gases in optical lattices.

My main results regards the development of a non-conventional diagrammatic technique for strongly interacting electron systems, based on the cumulant expansion, while regarding the quantum transport I developed the idea of a quantum pump for quantum information processes.

My research activity develops along the following lines::

• Study of strongly correlated electron models;
• Study of magnetic properties of spin ½ chains and ladders;
• Spin transport properties in mesoscopic systems in nanostructures;
• Interacting quantum gases: interaction, disorder and transport effects.
