Topological Phases in Perovskite Iridates with Strong Spin-Orbit Coupling
… a new class of metals dubbed “topological crystalline metals” with surface states protected by lattice symmetry and a pair of topological invariants. We show that these novel metallic phases can give rise to various non-trivial topological phases when different symmetries are broken, including a …

Quantum oscillations in Dirac semimetals
Dirac semimetals have recently gained interest due to their unique experimental signatures many of which can be explained by the topologically non-trivial band structure in these materials. Among the many candidates, the tellurides NbTe₄, TaPtTe₅ and TaNiTe₅ appear to provide a promising platform …

Manipulation and analysis of topological properties in hybrid Dirac materials [Manipolazione ed analisi delle proprietà topologiche dei materiali di Dirac]
… vengono studiati due tipi di sistemi: i semimetalli a linea nodale ingegnerizzati tramite campi Floquet e le eterostrutture superconduttive a base di grafene. Nella prima parte della tesi, studiamo gli stati di interfaccia che emergono quando due regioni di un semimetallo a linea nodale …
