Since the energy of the ground state (perturbed as well as unperturbed) is a quantity proportional to the volume Ω for Ω large and fixed density one already sees that for

As discussed in the main text, the distribution of the work is universal, i.e., it is independent on the system size N as well as the Fermi energy; it depends solely on

For simplicity, we assume the Doppler limit, neglect the variation of the Gaussian over the atomic line shape, and also neglect the power broadening due to the

For instance if the quantum system in question is an atom, then without external perturbation it is in its ground state, and only the ground state amplitude will be different
