This paper gives a theoretical framework for the work statistics of sudden quantum quenches in translation-invariant quadratic fermionic chains, linking them to traces of powers of Haar unitaries. Its main contribution is identifying when non-Gaussian fluctuations arise, specifically with many interaction terms, slowly decaying interactions, and Fisher-Hartwig singularities. It is fundamental many-body physics rather than a demonstrated device, so its relevance to quantum technology (e.g., quantum thermodynamics or energy-transfer control) is prospective.
