• Abstract summary: We investigate SSH-based charging protocols of quantum batteries with N quantum cells. This SSH QB hopping interaction induced ground state splitting makes the different effects of the dimerize parameter to the QB. Although we have enhanced energy and ergotropy by the dimerize parameter, QB's capacity will decrease.

• Abstract: The Su-Schrieffer-Heeger (SSH) model has recently received considerable attention in condensed matter because it describes a typical one-dimensional system with topological edge states. Here, we investigate SSH-based charging protocols of quantum batteries (QB) with N quantum cells. This SSH QB hopping interaction induced ground state splitting makes the different effects of the dimerize parameter to the QB in the different quantum phase region. In the non-splitting region, the dimerize parameter has little influence on the QB. Whereas the fully-splitting region, the dimerize parameter has a significantly quantum advantage to the energy and ergotropy in the ground state fully splitting region, which leads the dimerize spin couples will have larger occupations than other spins. Although we have enhanced energy and ergotropy by the dimerize parameter, QB's capacity will decrease.
