Self-consistent self-energy analysis of photoemission data
A. A. Kordyuk, S. V. Borisenko, A. Koitzsch +3
Here we present the details of a self-consistent procedure of the photoemission data analysis within the self-energy approach introduced in Ref.1 (cond-mat/0405696). We derive the…
Bare electron dispersion from photoemission experiments
A. A. Kordyuk, S. V. Borisenko, A. Koitzsch +3
Performing an in-depth analysis of the photoemission spectra along the nodal direction of the high temperature superconductor Bi-2212 we have developed a procedure to determine the…
Manifestation of the magnetic resonance mode in the nodal quasiparticle lifetime in superconducting cuprates
A. A. Kordyuk, S. V. Borisenko, A. Koitzsch +9
Studying the nodal quasiparticles in superconducting cuprates by photoemission with highly improved momentum resolution, we show that a new "kink" feature in the scattering rate is…
Change of quasiparticle dispersion in crossing T_c in the underdoped cuprates
T. Eckl, W. Hanke, S. V. Borisenko +5
One of the most remarkable properties of the high-temperature superconductors is a pseudogap regime appearing in the underdoped cuprates above the superconducting transition temper…
Origin of the shadow Fermi surface in Bi-based cuprates
A. Koitzsch, S. V. Borisenko, A. A. Kordyuk +11
We used angle-resolved photoemission spectroscopy to study the shadow Fermi surface in one layer Bi2Sr1.6La0.4CuO6+delta and two layer (Bi,Pb)2Sr2CaCu2O8+delta. We find the shadow…
