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…
Interaction-driven quantum phase transition of a single magnetic impurity in Fe(Se,Te)
M. Uldemolins, A. Mesaros, G. D. Gu +4
Understanding the interplay between individual magnetic impurities and superconductivity is crucial for bottom-up construction of novel phases of matter. For decades, the descripti…
Quasiparticle focusing of bound states in two-dimensional -wave superconductors
Mateo Uldemolins, Andrej Mesaros, Pascal Simon
A magnetic impurity on a superconducting substrate induces in-gap Yu-Shiba-Rusinov (YSR) bound states, whose intricate spatial structure crucially influences the possibilities of e…
