parafermions in weakly interacting superconducting constrictions at the helical edge of quantum spin Hall insulators
C. Fleckenstein, N. Traverso Ziani, B. Trauzettel
Parafermions are generalizations of Majorana fermions that may appear in interacting topological systems. They are known to be powerful building blocks of topological quantum compu…
The invisible Majorana bound state at the helical edge
Christoph Fleckenstein, Felix Keidel, Bjoern Trauzettel +1
The presence of a Majorana bound state in condensed matter systems is often associated to a zero bias peak in conductance measurements. Here, we analyze a system were this paradigm…
Detection of fractional solitons in quantum spin Hall systems
C. Fleckenstein, N. Traverso Ziani, B. Trauzettel
We propose two experimental setups that allow for the implementation and the detection of fractional solitons of the Goldstone-Wilczek type. The first setup is based on two magneti…
Conductance signatures of odd-frequency superconductivity in quantum spin Hall systems using a quantum point contact
C. Fleckenstein, N. Traverso Ziani, B. Trauzettel
Topological superconductors give rise to unconventional superconductivity, which is mainly characterized by the symmetry of the superconducting pairing amplitude. However, since th…
