Relative error of the mean extractable work for the first-order correction to the eigenenergies’ 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) Dynamics is generated by standard zero-order perturbation theory. (b) Dynamics is generated by KS-based zero-order perturbation theory using the PLDA approximation for the exchange-correlation potential. (c) Dynamics is generated by KS-based zero-order perturbation theory using an accurate parametrization for the exact correlation energy E c .
