摘要: We discuss the spin-dynamics in spin-1/2 antiferromagnetic Heisenberg model and related quantum nonlinear σ on square-lattice at zero low temperatures. use mainly numerical methods, including variational Monte Carlo, Carlo exact diagonalization techniques. compare our results to those obtained by other techniques certain experimental data undoped copper-oxygen insulators. Effects of hole-doping are briefly summarized framework strong-coupling Hubbard model.
