Frequency-dependent spin susceptibility in the two-dimensional Hubbard model

Abstract

A Quantum Monte Carlo calculation of dynamical spin susceptibility in the half-filled 2D Hub-bard 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 Mat-subara Green's function into the real frequency domain and in deriving the… (More)
