Quantum metric quadrupoles in elemental bismuth thin films
Rhonald Burgos Atencia, Pavlo Makushko, Gabriele Naselli +11
The authors demonstrate that third-order nonlinear electrical transport in centrosymmetric bismuth thin films originates from quantum metric quadrupoles, and they experimentally ob…

Topological properties of domain walls in antiferromagnetic topological insulators
Gabriele Naselli, Ion Cosma Fulga
Motivated by the study of stacking faults in weak topological insulators and the observation of magnetic domain walls in MnBiTe, we explore the topological properti…

Stability of Weyl node merging processes under symmetry constraints
Gabriele Naselli, György Frank, Dániel Varjas +4
Changes in the number of Weyl nodes in Weyl semimetals occur through merging processes, usually involving a pair of oppositely charged nodes. More complicated processes involving m…
