  journal={Physical Review B},
Performing an in-depth analysis of the photoemission spectra along the nodal direction of the hightemperature superconductor Bi-2212 we developed a procedure to determine the underlying electronic structure and established a precise relation of the measured quantities to the real and imaginary parts of the self-energy of electronic excitations. The self-consistency of the procedure with respect to the Kramers-Kronig transformation allows us to draw conclusions on the applicability of the… Expand

About the relation between the quasiparticle Green's function in cuprates obtained from ARPES data and the magnetic susceptibility
Abstract Angle resolved photoemission spectroscopy (ARPES) provides a detailed view of the renormalized band structure in cuprates and, consequently, is a key to the self-energy and the quasiparticleExpand
An ARPES view on the high-Tc problem: Phonons vs. spin-fluctuations
Abstract. We review the search for a mediator of high-Tc superconductivity focusing on ARPES experiment. In case of HTSC cuprates, we summarize and discuss a consistent view of electronicExpand
Theoretical Investigation of the Feasibility of Electronic Mechanism for Superconducting Pairing in Overdoped Cuprates
Cooper’s formalism for the fermionic pairing has been revisited considering up to third-neighbour hopping terms, firstly with a Fermi liquid-like background on a square lattice keeping in mind theExpand
Electron spectrum in high-temperature cuprate superconductors
A microscopic theory for the electron spectrum of the CuO2 plane within an effective p-d Hubbard model is proposed. The Dyson equation for the single-electron Green’s function in terms of the HubbardExpand
