Origin of the crossover from polarons to Fermi liquids in transition metal oxides

Photoemission spectroscopy studies of anatase titanium oxide have demonstrated a doping-driven crossover in the polaronic character of charge carriers. Here, the authors obtain a first principles understanding of these observations in terms of plasma screening and electron–phonon coupling.
