Life of the nodal quasiparticles in Bi-2212 as seen by ARPES
A. A. Kordyuk, S. V. Borisenko, A. Koitzsch +4
While the pronounced doping dependence of the quasiparticle spectral weight in the antinodal region of the superconducting cuprates, as seen by ARPES, unambiguously points to the m…
Parity of the Pairing Bosons in a High-Temperature Superconductor
S. V. Borisenko, A. A. Kordyuk, A. Koitzsch +10
We report the observation of a novel effect in the bilayer Pb-Bi2212 high-TC superconductor by means of angle-resolved photoemission with circularly polarized excitation. Different…
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…
