Topological state engineering by potential impurities on chiral superconductors
Vardan Kaladzhyan, Joel Röntynen, Pascal Simon +1
In this work we consider the influence of potential impurities deposited on top of two-dimensional chiral superconductors. As discovered recently, magnetic impurity lattices on an…
Chern mosaic - topology of chiral superconductivity on ferromagnetic adatom lattices
Joel Röntynen, Teemu Ojanen
In this work we will explore the properties of superconducting surfaces decorated by two-dimensional ferromagnetic adatom lattices. As discovered recently [Röntynen and Ojanen, Phy…
Tuning topological superconductivity in helical Shiba chains by supercurrent
Joel Röntynen, Teemu Ojanen
Recent experimental investigations of arrays of magnetic atoms deposited on top of a superconductor have opened a new chapter in the search of topological superconductivity. We gen…
Majorana states in helical Shiba chains and ladders
Kim Pöyhönen, Alex Westström, Joel Röntynen +1
Motivated by recent proposals to realize Majorana bound states in chains and arrays of magnetic atoms deposited on top of a superconductor, we study the topological properties of v…
