Abstract: 

The main objective of this thesis is to explore new perspectives on topological and moiré Dirac matter. First, the emergence of magic angle physics and moiré superlattices is reported in one-dimensional structures, namely chiral collapsed carbon nanotubes. Second, regarding topological Dirac materials, the robustness of the surface states displayed by topological insulators protected by crystalline symmetries is studied when impurities are introduced. Finally, other types of topology are explored; new two-dimensional and threefold-symmetric material candidates hosting fragile topology are presented, with experimentally feasible signatures.
