Abstract

We analyze a minimal model of SrTiO3, such as has been historically used to\nanalyze the superconducting state. Treating the electron-phonon and\nelectron-electron interactions on an equal footing, we calculate the normal\nstate properties, focusing on the spectral function. We find a density-driven\ncrossover caused mostly by the adiabaticity of the bosonic modes, but the\nspectral features of our theory are dominated by coupled plasmon-phonon\noscillations rather than the bare phonon features seen in experiment.\n
