Topological phase transition driven by structural defects
Andrii Syrota, Andrej Mesaros, Pascal Simon
Structural defects, such as disclinations and dislocations, destroy the long-range crystalline order as they proliferate. In this work, we continuously drive a system from a crysta…

Impurity as a probe of Berry curvature and wavefunction winding in gapped two-band models
Reda Nabil, Pascal Simon, Andrej Mesaros
We explore the possibility of using quasiparticle interference near impurities to extract non-local properties of bands. Focusing on the minimal two-band description of a system wi…
