About Us

The Quantum Transport group aims at the understanding and prediction of novel quantum transport phenomena in low-dimensional systems, arising from the interplay of electronic correlations, topological effects, geometric frustration and peculiar density of states.

Our work is mainly theoretical and numerical. We have developed our own computational packages that let us address a wide variety of interacting and non-interacting electronic models in a completely visual way.

Our research has recently focused on high-root topological insulators (a generalisation of square-root topological insulators that can be implemented in photonic, acoustic and magnetic artificial lattices) and on applications to topological quantum computing.

The group is part of the Theoretical and Computational Physics (TCP) group of the i3N – Institute for Nanostructures, Nanomodelling and Nanofabrication.
