dc.description©IOP Publishing Ltd.. We are grateful to J.H. Jefferson, G. Aeppli, A. Bratkovsky and V. Kabanov for stimulating discussions. This research was funded by an SERC grant GR/J18675 and our general development of SVD techniques by the US Army Research Office, agreement no. DAAL03-92-G-0142. Two of the authors (CEC and PEK) were supported by EPSRC and ORS - University of London respectively.
dc.description.abstractA Quantum Monte Carlo calculation of dynamical spin susceptibility in the half-filled 2D Hubbard model is presented for temperature T = 0.2t and an intermediate on-site repulsion U = 4t. Using the singular value decomposition technique we succeed in analytically continuing the Matsubara Green’s function into the real frequency domain and in deriving the spectral representation for the longitudinal and transverse spin susceptibility. The simulation results, while contradicting the random-phase approximation prediction of antiferromagnetic long-range order at this temperature, are in agreement with an extension of a self-consistent renormalization approach of Moriya. The static susceptibility calculated using this technique is qualitatively consistent with the ω → 0 simulation results.
