    “…In this study, we address whether the substorm process contributes a significant amount of energy to the ring current. The ring current is a highly variable region, and understanding the energization processes provides valuable insight into how substorm‐ring current coupling may contribute to the generation of storm conditions and provide a source of energy for wave driving. …”

    “…By employing accurate state‐of‐the‐art many‐electron quantum‐chemistry methods, we establish that monocyclic carbon rings can accommodate Li guest atoms. The low‐lying electronic states of these endocircular systems are analyzed and found to include both charge‐separated states where the guest Li atom appears as a cation and the ring as an anion and encircled‐electron states where Li and the ring are neutral. …”
