Query: Single hole spectral function and spin-charge separation in the t-J
  model   Worm algorithm quantum Monte Carlo simulations of the hole Green function
with subsequent spectral analysis were performed for J/t 0.1, 0.2, 0.4 on
lattices with up to LxL=32x32 sites at temperatures as low as T=J/40, and
present, apparently, the hole spectral function in the thermodynamic limit.
Spectral analysis reveals a delta-function-sharp quasiparticle peak at the
lower edge of the spectrum which is incompatible with the power-law singularity
and thus rules out the possibility of spin-charge separation in this parameter
range. Spectral continuum features two peaks separated by a gap ~4t.
