Relative error of the mean extracted work for the ‘zero-order’ perturbation protocol. Contour plot of the relative error is shown as function of the dimensionless particle-particle interaction strength U/J and the dimensionless evolution time τ × J. (a) Standard zero-order perturbation theory. (b) KS-based zero-order perturbation theory using the PLDA approximation for the exchange-correlation potential. (c) KS-based zero-order perturbation theory using an accurate parametrization for the exact E c .
