Query: Common Fermi-liquid origin of T-squared resistivity and
  superconductivity in n-type SrTiO3   A detailed analysis is given of the T^2 term in the resistivity observed in
electron-doped SrTiO3. Novel bandstructure data are presented, which provide
values for the bare mass, density of states, and plasma frequency of the
quasiparticles as a function of doping. It is shown that these values are
renormalized by approximately a factor 2 due to electron-phonon interaction. It
is argued that the quasiparticles are in the anti-adiabatic limit with respect
to electron-phonon interaction. The condition of anti-adiabatic coupling
renders the interaction mediated through phonons effectively non-retarded. We
apply Fermi-liquid theory developed in the 70's for the T^2 term in the
resistivity of common metals, and combine this with expressions for Tc and with
the Brinkman-Platzman-Rice (BPR) sum-rule to obtain Landau parameters of n-type
SrTiO3. These parameters are comparable to those of liquid 3He, indicating
interesting parallels between these Fermi-liquids despite the differences
between the composite fermions from which they are formed.
