Evidence for ubiquitous strong electron-phonon coupling in high-temperature superconductors
A. Lanzara, P. V. Bogdanov, X. J. Zhou +12
Coupling between electrons and phonons (lattice vibrations) drives the formation of the electron pairs responsible for conventional superconductivity. The lack of direct evidence f…
Electron-Like Fermi Surface and Remnant (pi,0) Feature in Overdoped La1.78Sr0.22CuO4
T. Yoshida, X. J. Zhou, M. Nakamura +13
We have performed an angle-resolved photoemission study of overdoped La1.78Sr0.22CuO4, and have observed sharp nodal quasiparticle peaks in the second Brillouin zone that are compa…
Dual Nature of the Electronic Structure of the Stripe Phase
X. J. Zhou, T. Yoshida, S. A. Kellar +11
High resolution angle-resolved photoemission measurements have been carried out on (La_1.4-xNd_0.6Sr_x)CuO_4, a model system with static stripes, and (La_1.85Sr_0.15)CuO_4, a high…
ARPES study of Pb doped Bi_2Sr_2CaCu_2O_8 - a new Fermi surface picture
P. V. Bogdanov, A. Lanzara, X. J. Zhou +7
High resolution angle resolved photoemission data from Pb doped Bi_2Sr_2CaCu_2O_8 (Bi2212) with suppressed superstructure is presented. Improved resolution and very high momentum s…
Evidence for an energy scale for quasiparticle dispersion in Bi_2Sr_2CaCu_2O_8
P. V. Bogdanov, A. Lanzara, S. A. Kellar +8
Quasiparticle dispersion in is investigated with improved angular resolution as a function of temperature and doping. Unlike the linear dispersion predi…
