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…
Impurity-dependent quantum geometry in 2D flat band superconductors
Simão S. Cardoso, A. Mesaros, P. Simon
In flat band superconductors, quantum geometry, rather than kinetic energy, governs pairing and transport. However, how this geometry manifests in the response to a local, individu…
Detecting the topological winding of superconducting nodes via Local Density of States
Lena Engström, Pascal Simon, Andrej Mesaros
Many systems are topologically trivial in the bulk, but still have non-trivial wavefunctions locally in the Brillouin zone. For example, in a small-gap Dirac material the Berry cur…
Anisotropy of Yu-Shiba-Rusinov states in NbSe
Mateo Uldemolins, Freek Massee, Tristan Cren +2
The spatial structure of in-gap Yu-Shiba-Rusinov (YSR) bound states induced by a magnetic impurity in a superconductor is the essential ingredient for the possibility of engineerin…
Topologically trivial gap-filling in superconducting Fe(Se,Te) by one dimensional defects
A. Mesaros, G. D. Gu, F. Massee
Structural distortions and imperfections are a crucial aspect of materials science, on the macroscopic scale providing strength, but also enhancing corrosion and reducing electrica…
