Possible mechanism for superconductivity in doped SrTiO_{3}

The soft ferroelectric phonon in SrTiO_{3} observed with optical spectroscopy has an extraordinarily strong spectral weight which is much stronger than expected in the limit of a perfectly ionic compound. This “charged phonon” effect in SrTiO_{3} is caused by the close-to-covalent character of the T...
