摘要：

The magnetocaloric Effect (MCE) of a quantum pseudodot was investigated by considering the influence of spin-orbit interaction (SOI). The entropy and internal energy change have been calculated using the Tsallis formulation. Our results reveal that both the SOI effect and external parameters have a significant impact on the entropy and internal energy changes of a quantum pseudodot. It is important to note that the MCE is closely linked to the behavior of the magnetic dipoles, and the presence of external magnetic fields and SOI exert considerable influence on the entropy change, both analytically and numerically. Additionally, our results highlight the sensitivity of the MCE to the extensivity parameter q.
