ARPES Study of the Superconducting Gap Anisotropy in Bi_2Sr_2CaCu_2O_8+x
H. Ding, M. R. Norman, J. C. Campuzano +6
We report measurements of the momentum dependence of the superconducting gap in Bi_2Sr_2CaCu_2O_{8+x} (Bi2212) with angle-resolved photoemission spectroscopy using a dense sampling…
Polarization Selection Rules and Superconducting Gap Anisotropy in
M. R. Norman, M. Randeria, H. Ding +2
We discuss polarization selection rules for angle-resolved photoemission spectroscopy in Bi2212. Using these we show that the ``hump'' in the superconducting gap observed in the $X…
Phenomenological Models for the Gap Anisotropy of Bi-2212 as Measured by ARPES
M. R. Norman, M. Randeria, H. Ding +1
Recently, high resolution angle-resolved photoemission spectroscopy has been used to determine the detailed momentum dependence of the superconducting gap in the high temperature s…
Symmetry of the Gap in Bi2212 from Photoemission Spectroscopy
M. R. Norman
In a recent Letter, Shen et al have detected a large anisotropy of the superconducting gap in Bi2212, consistent with d-wave symmetry, from photoemission spectroscopy. Moreover, th…
