Quantum Monte Carlo study of the itinerant-localized model of strongly correlated electrons: Spin-spin correlation functions
arXiv:1608.02298 · doi:10.1103/PhysRevB.94.235118
Abstract
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.
