Theory of the leading edge gap in underdoped cuprates
We present the theory of the leading edge gap in the normal state of
underdoped high- materials. The consideration is based on a magnetic
scenario for cuprates. We show that as doping decreases, the increasing
interaction with paramagnons gives rise to a near destruction of the Fermi
liquid and this in turn yields precursors to wave pairing. We argue that
the leading edge gap at and a broad maximum in the spectral
function at are byproducts of the same physical phenomenon.Comment: 4 pages, revtex, two figure
