Phys.org  November 30, 2024 Researchers in Italy investigated the performance of a one-dimensional dimerized chain as a spin quantum battery. Integrable model showed a rich quantum phase diagram that emerged through a mapping of the spins onto auxiliary fermionic degrees of freedom. They used a charging protocol relying on the double quench of an internal parameter, the strength of the dimerization, and addressed the energy stored in the systems. They observed three distinct regimes, depending on the timescale characterizing the duration of the charging: a short-time regime related to the dynamics of the single dimers, a long-time regime related to […]
