In addition, collective modes can emerge in a system of ions moving within a singleparticle potential energy surface. When strong ion-ion interactions constrain the ions to be spaced apart in a manner inconsistent with the energy landscape, a smoother energy landscape is experienced by the group as a whole as not all moving ions can be at equivalent extrema of the potential energy surface at the same time. These collective modes, if formed and mobile, dominate transport statistically over individual ion hops due to their higher barriers. To achieve fast ion conduction, it is important to engineer a high intrinsic concentration of mobile carriers by inducing frustration, which breaks symmetries and maximizes geometric frustration in the sublattice. Frustration flattens the energy landscape, preventing the trapping of mobile carriers in deep energy minima and promoting exploration of degenerate states within a narrow energy window, resulting in a high concentration of mobile charge carriers and high interstate transition rates.
