A falling magnetic monopole as a local quench

We look at the free fall of a magnetic monopole in Poincaré AdS$_4$ as a holographic model of local quench in a strongly coupled CFT$_3$ activated by the insertion of a condensing scalar operator.
Comparing with the setup obtained by replacing the monopole with a black hole, we probe to what extent the physics of the quench is sensitive to the features of the falling object.
As a result, we argue that in case the energy of the dual quenches is conserved, the holographic energy-momentum tensor holds the same functional form in both configurations. Instead, the spreading of entanglement driven by the quench drastically changes. We comment on the implications of such outcomes on the validity of the first law of entanglement entropy.
