SUMMARY:Interactions and superconductivivity in the polaronic Fermi li
 quid SrTiO<sub>3</sub>\, R. G. Herb Condensed Matter Seminar\, Dirk va
 n der Marel\, University of Geneva
DESCRIPTION:SrTiO<sub>3</sub> is a semiconductor which\, when doped wi
 th a low density of electrons\,  becomes superconducting with a dome-s
 haped doping dependence of the superconducting transition temperature.
  I will present optical\, transport and specific heat data\, and discu
 ss a unified approach to the transport properties and superconductivit
 y\, showing that superconductivity emerges out of a liquid of interact
 ing polarons. This interaction is rather weak\, disfavouring the pictu
 re of uncondensed bipolarons above Tc.
