AbstractParticle-like topological structures such as polar skyrmions in ferroelectrics have the potential for application in high-density information storage. Since the polar topologies arise from a complicated competitive energy balance, such non-trivial topological states are difficult to manipulate by applying non-persistent external stimuli, such as bias or strain. Thus, a flexible strategy for manipulating topological polar states is needed to realize ultrahigh-density topological devices.
