In a Kitaev chain, a mobile impurity undergoes a sharp polaron-to-molecule transition when the host is topologically trivial and a smooth crossover when the host is topological, a possible bulk topology signature.

abstract
This work re-analyzes Gul et al. Nature Nanotechnology 2018 "Ballistic Majorana nanowire devices" using fuller data from the original experiments released in 2023 on Zenodo. The authors have prepared a correction to their article that appeared in Nature Nanotechnology in 2024. However, the correction does not address the concerns we identify here. We demonstrate that the fuller data contain extensive evidence for quantum dots and disorder that are completely inconsistent with the authors' conclusion that they have achieved ballistic devices containing zero bias peaks of likely Majorana origin. We show how data selection, data cropping and undisclosed data processing played a role in composing the figures of the final published paper.

A Mobile Impurity in the Kitaev Chain: Phase Diagram and Signatures of Topology
In a Kitaev chain, a mobile impurity undergoes a sharp polaron-to-molecule transition when the host is topologically trivial and a smooth crossover when the host is topological, a possible bulk topology signature.
