Query: Quantum Monte Carlo study of the itinerant-localized model of strongly
  correlated electrons: Spin-spin correlation functions   We perform quantum Monte Carlo simulations of the itinerant-localized
periodic Kondo-Heisenberg model for the underdoped cuprates to calculate the
associated spin correlation functions. The strong electron correlations are
shown to play a key role in the abrupt destruction of the quasi long-range
antiferromagnetic order in the lightly doped regime.
