Theory of local topological markers for finite and periodic two-dimensional systems
Nicolas Baù, Antimo Marrazzo
The topological phases of two-dimensional time-reversal symmetric insulators are classified by a topological invariant. Usually, the invariant is introduced and ca…

Spectral Operator Representations
Austin Zadoks, Antimo Marrazzo, Nicola Marzari
Machine learning in atomistic materials science has grown to become a powerful tool, with most approaches focusing on atomic arrangements, typically decomposed into local atomic en…

Spin-dependent interactions in orbital-density-dependent functionals: non-collinear Koopmans spectral functionals
Antimo Marrazzo, Nicola Colonna
The presence of spin-orbit coupling or non-collinear magnetic spin states can have dramatic effects on the ground-state and spectral properties of materials, in particular on the b…
