Trapped-ion quantum simulators can now realize and characterize polarons—charge carriers dressed in phonon clouds—using programmable spin-phonon interactions and novel displaced Green's functions for spectroscopy in previously inaccessible regimes.

Ultracold-atom collision study reveals sharply enhanced dynamical inertia of fast impurities in Bose-Einstein condensates near resonance, providing evidence for many-body polaron dressing in strongly coupled quantum regimes.
