| contents | In the context of energy storage at the nanoscale, exploring the notion of \textit{quantum advantage} implies walking on the thin line at the boundary between quantum mechanics and thermodynamics, which underpins our conventional understanding of battery devices. With no classical analogue, the Sachdev-Ye-Kitaev (SYK) model has emerged in the last years as a promising platform to boost charging and storage efficiency thanks to its highly-entangling dynamics. Here, we explore how the robustness of this setup by considering the sparse version of the SYK model, showing that, as long as chaos is not completely broken, reducing its complexity may lead to more efficient quantum batteries. |
