We study how electrons behave in quantum materials.

We are a theory group in the Department of Physics and Astronomy at the University of Bologna. Our work is about the geometry of electronic wave functions and the topological phases it gives rise to, what happens when interactions between electrons become strong, and how electrons couple to the vibrations of the lattice. We use analytical theory, numerical calculations and, increasingly, machine learning.

Research

Topology and Berry curvatureThe geometry of electronic wave functions and the topological phases it produces.
Strongly correlated electronsSlave-spin and related methods for correlated metals and Mott physics.
Electron–phonon coupling and polaronsHow electrons dress themselves with lattice vibrations.
Machine learning for materialsData-driven models trained on first-principles calculations.

All research

Band structure of the kagome lattice in a nearest-neighbour tight-binding model. The two dispersive bands touch at a Dirac point at K; the third band is flat.
