Topological Fractional Pumping in Optical Lattice
Prof. Rosario Fazio
International Center for Theoretical Physics (ICTP), Italy

Alkaline-earth(-like) ultracold atoms, trapped in optical lattices and in the presence of an external gauge field, can stabilise Mott insulating phases characterised by density and magnetic order. This property can be used to realise a topological fractional pump. I will describe the most important properties of these systems and how to realise a topological pump.

About the Speaker

Prof. Rosario Fazio obtained his PhD degree from the University of Catania in 1989, where he became Assistant Professor in 1990 and Associate Professor in 1998. He moved in 2001 to the Scuola Normale Superiore in Pisa, and in 2005 became full Professor in SISSA, Trieste. He returned to the Scuola Normale Superiore in 2008, of which he is still Professor of Condensed Matter Physics. In 2016 he became the Head of the Condensed Matter and Statistical Physics Sector of ICTP. Currently, he is also a Visiting Professor at the Center for Quantum Technologies, National University of Singapore. His main research interests are on quantum transport in nanostructures, superconductivity (Josephson junction arrays, superconducting nanocircuits), quantum simulators (cold atoms in optical lattices, QED-arrays), non-equilibrium dynamics of many-body systems, and quantum information processing.
