    "abstract": "We revisit from a quantum-information perspective a classic problem of\npolaron theory in one dimension. In the context of the Holstein model we show\nthat a simple analysis of quantum entanglement between excitonic and phononic\ndegrees of freedom allows one to effectively characterize both the small and\nlarge polaron regimes as well as the crossover in between. The small (large)\npolaron regime corresponds to a high (low) degree of bipartite quantum\nentanglement between the exciton and the phonon cloud that clothes the exciton.\nMoreover, the self-trapping transition is clearly displayed by a sharp drop of\nexciton-phonon entanglement.",
