Localization pattern of a mobile impurity in the disordered Kitaev chain
A. V. Sadovnikov, A. N. Rubtsov
We study a mobile impurity coupled to a Kitaev chain with chemical-potential disorder and ask whether the impurity behavior distinguishes different regimes of the host system. Exac…

A Mobile Impurity in the Kitaev Chain: Phase Diagram and Signatures of Topology
A. V. Sadovnikov, M. S. Bahovadinov, A. N. Rubtsov +1
We study the physics of a mobile impurity immersed in a topological superconductor. We discuss the system's phase diagram obtained with exact diagonalization. We argue that th…
