On the determination of the Fermi surface in high-Tc superconductors by angle-resolved photoemission spectroscopy

J. Mesot, M. Randeria, M. R. Norman +13

We study the normal state electronic excitations probed by angle resolved photoemission spectroscopy (ARPES) in Bi2201 and Bi2212. Our main goal is to establish explicit criteria f…

Electronic Spectra and Their Relation to the (pi,pi) Collective Mode in High-Tc Superconductors

J. C. Campuzano, H. Ding, M. R. Norman +15

Photoemission spectra of Bi2Sr2CaCu2O8 reveal that the high energy feature near (pi,0), the "hump", scales with the superconducting gap and persists above Tc in the pseudogap phase…

Superconducting Gap Anisotropy and Quasiparticle Interactions: a Doping Dependent ARPES Study

J. Mesot, M. R. Norman, H. Ding +11

Comparing ARPES measurements on Bi2212 with penetration depth data, we show that a description of the nodal excitations of the d-wave superconducting state in terms of non-interact…

Temperature-induced spectral weight transfer in Bi_2Sr_2CaCu_2O_{8+delta}: a conventional view

J. C. Campuzano, H. Ding, H. Fretwell +6

In contrast with the recent photoemission observations by Shen et al. of anomalous temperature-induced momentum-dependent spectral weight transfer in Bi_2Sr_2CaCu_2O_{8+delta}, we…

ARPES study of the superconducting gap and pseudogap in Bi2Sr2CaCu2O8+x

H. Ding, J. C. Campuzano, M. R. Norman +8

In this paper, we review some of our ARPES results on the superconducting and pseudo gaps in Bi2Sr2CaCu2O8+x. We find that optimally and overdoped samples exhibit a d-wave gap, whi…

Destruction of the Fermi Surface in Underdoped High Tc Superconductors

M. R. Norman, H. Ding, M. Randeria +8

The Fermi surface is a central concept in the theory of metals. Even though the optimally doped high temperature superconductors exhibit an anomalous normal state, angle resolved p…
