• describe the energy fluctuations produced by the quench, providing an accurate and detailed insight into the fundamental physics of the process. We present here a numerical approach to the non-equilibrium work distribution, supported by applications to phenomena occurring at very diverse energy ranges. One

• thermodynamics; orthogonality catastrophe; sudden quench; ultra-cold Fermi gases; work distribution; Introduction Closed many-particle systems and their out-of-equilibrium dynamics after a quench have been attracting considerable interest over the past years, with particular attention to the brutal disturbance

• absorption and emission spectra from noninteracting quantum dots have been interpreted in terms of the quantum work distribution, and linked to the corresponding fluctuation relations in statistical mechanics [36]. To explore more of such a connection, we present here a comparison of the statistics of the
