Query: Effective tight-binding model for renormalized band structure of Sr2RuO4   We derive an effective quasiparticle tight-binding model which is able to
describe with high accuracy the low-energy electronic structure of Sr2RuO4
obtained by means of low temperature angle resolved photoemission spectroscopy.
Such approach is applied to determine the momentum and orbital dependent
effective masses and velocities of the electron quasiparticles close to the
Fermi level. We demonstrate that the model can provide, among the various
computable physical quantities, a very good agreement with the specific heat
coefficient and the plasma frequency. Its use is underlined as a realistic
input in the analysis of the possible electronic mechanisms related to the
superconducting state of Sr2RuO4.
