Query: Integral charge quasiparticles in a fractional quantum Hall liquid   Starting from a collective description of the incompressible fractional
quantum Hall liquid as an elastic medium that supports gapped neutral
excitations I show that the one-electron spectral function of this system
exhibits a sharp peak at the lowest available excitation energy, well separated
from the continuum spectrum at higher energy. I interpret this peak as the
signature of the integral charge quasiparticle recently predicted by Peterson
and Jain\cite{Jain05}, and calculate its spectral weight for different filling
factors.
