Nature of the Electronic Excitations near the Brillouin Zone Boundary of BiSrCaCuO
D. L. Feng, C. Kim, H. Eisaki +12
Based on angle resolved photoemission spectra measured on different systems at different dopings, momenta and photon energies, we show that the anomalously large spectral linewidth…
Signature of Superfluid Density in the Single-Particle Excitation Spectrum of Bi2Sr2CaCu2O8+delta
D. L. Feng, D. H. Lu, K. M. Shen +12
We report that the doping and temperature dependence of photoemission spectra near the Brillouin zone boundary of Bi2Sr2CaCu2O8+delta exhibit unexpected sensitivity to the superflu…
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…
Resonant Spin Excitation in an Overdoped High Temperature Superconductor
H. He, Y. Sidis, P. Bourges +8
An inelastic neutron scattering study of overdoped Bi_2Sr_2CaCu_2O_{8+δ} $ (T_c = 83 K) has revealed a resonant spin excitation in the superconducting state. The mode energy is E_r…
