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 P.M. has been supported by the Spanish MINECO (FIS2017-84114-C2-1- P), and EU FEDER Quantumcat Postprint (published version) Mobile impurities Topological transport of mobile impurities
