In the past year, the grant was used for work in the field of topological phases, with emphasis on finding new many-body states of matter, new many-body methods to analyze them and new phenomena that would happen in the presence of interactions on the surface of topological insulators. In the past 3 years, we have started a new direction, that of fractional topological insulators. These are materials in which a topologically nontrivial quasi-flat band is fractionally filled and then subject to strong interactions.
