Nonuniform superconducting states from Majorana flat bands
Sushanth Varada, Aksel Kobiałka, Ankita Bhattacharya +2
Zero-energy flat bands within the superconducting gap can give rise to competing ordered phases. We investigate such phases in topological superconductors based on the magnetic ada…
Unconventional topological transitions in a self-organized magnetic ladder
Maciej M. Maśka, Nicholas Sedlmayr, Aksel Kobiałka +1
It is commonly assumed that topological phase transitions in topological superconductors are accompanied by a closing of the topological gap or a change of the symmetry of the syst…
Majorana Bound State leakage to impurity in Su-Schrieffer-Heeger-Rashba scenario
A. Kobiałka, A. Ptok
We show anomalous features of Majorana Bound State leakage in the situation where topological Rashba nanowire is dimerized according to the Su-Schrieffer-Heeger (SSH) scenario and…
Dimerization-induced topological superconductivity in a Rashba nanowire
Aksel Kobiałka, Nicholas Sedlmayr, Maciej M. Maśka +1
We analyze influence of a dimerization on the topological phases of the Rashba nanowire proximitized to a superconducting substrate. We find that periodic alternations of the hoppi…
