Exchangeless braiding of Majorana zero modes in weakly coupled Kitaev chains
Robin Quade, Michael Potthoff
Exchangeless braiding of Majorana modes is studied in minimal networks of weakly hybridized Kitaev chains of finite length using a rigorous many-body framework. In particular, for…

Bound states and local topological phase diagram of classical impurity spins coupled to a Chern insulator
Simon Michel, Axel Fünfhaus, Robin Quade +2
The existence of bound states induced by local impurities coupled to an insulating host depends decisively on the global topological properties of the host's electronic structure.…

Controlling the real-time dynamics of a spin coupled to the helical edge states of the Kane-Mele model
Robin Quade, Michael Potthoff
The time-dependent state of a classical spin locally exchange coupled to an edge site of a Kane-Mele model in the topologically non-trivial phase is studied numerically by solving…
