Bi-layer splitting in overdoped high cuprates
Recent angle-resolved photoemission data for overdoped Bi2212 are explained.
Of the peak-dip-hump structure, the peak corresponds the component
of a hole condensate which appears at . The fluctuating part of this same
condensate produces the hump. The bilayer splitting is large enough to produce
a bonding hole and an electron antibonding quasiparticle Fermi surface. Smaller
bilayer splittings observed in some experiments reflect the interaction of the
peak structure with quasiparticle states near, but not at, the Fermi surface.Comment: 4 pages with 2 figures - published versio
Hyperspherical entanglement entropy
The coefficient of the log term in the entanglement entropy associated with
hyperspherical surfaces in flat space-time is shown to equal the conformal
anomaly by conformally transforming Euclideanised space--time to a sphere and
using already existing formulae for the relevant heat--kernel coefficients
after cyclic factoring. The analytical reason for the result is that the
conformal anomaly on the lune has an extremum at the ordinary sphere limit. A
proof is given. Agreement with a recent evaluation of the coefficient is found.Comment: 7 pages. Final revision. Historical comments amended. Minor remarks
