Modeling the Fermi arc in underdoped cuprates
arXiv:0708.1713 · doi:10.1103/PhysRevB.76.174501
Abstract
Angle resolved photoemission data in the pseudogap phase of underdoped cuprates have revealed the presence of a truncated Fermi surface consisting of Fermi arcs. We compare a number of proposed models for the arcs, and find that the one that best models the data is a d-wave energy gap with a lifetime broadening whose temperature dependence is suggestive of fluctuating pairs.
