Engineering 1D topological phases on -wave superconductors
Isac Sahlberg, Alex Westström, Kim Pöyhönen +1
In this work, we study how, with the aid of impurity engineering, two-dimensional -wave superconductors can be employed as a platform for one-dimensional topological phases. We…
Skyrmion-induced subgap states in p-wave superconductors
Kim Pöyhönen, Alex Westström, Sergey S. Pershoguba +2
In s-wave systems, it has been theoretically shown that a ferromagnetic film hosting a skyrmion can induce a bound state embedded in the opposite-spin continuum. In this work, we c…
Topological superconductivity and anti-Shiba states in disordered chains of magnetic adatoms
Alex Westström, Kim Pöyhönen, Teemu Ojanen
Regular arrays of magnetic atoms on a superconductor provide a promising platform for topological superconductivity. In this work we study effects of disorder in these systems, foc…
