dc.description.abstract
We study the Hall response of topologically trivial mobile impurities (Fermi polarons) interacting weakly
with majority fermions forming a Chern-insulator background. This setting involves a rich interplay between
the genuine many-body character of the polaron problem and the topological nature of the surrounding cloud.
When the majority fermions are accelerated by an external field, a transverse impurity current can be induced. To
quantify this polaronic Hall effect, we compute the drag transconductivity, employing controlled diagrammatic
perturbation theory in the impurity-fermion interaction
