Time-dependent fluctuating local field approach for description of the correlated fermions dynamics
TD-FLF reduces the time-dependent Schrödinger equation for correlated fermions to a generalized eigenvalue problem using a time-dependent distribution of a classical fluctuating field, yielding results close to exact diagonalization on half-filled 2D Hubbard lattices while outperforming mean-field.
