Polar topological textures are recently discovered in ultra-thin ferroelectrics, including stripe, labyrinth, or bubble states. Enabling to shape on-demand, these topologies can provide an original platform for potential applications. Here, using first-principle-based calculations, it is shown that THz electric field pulses are an efficient means for generating a plethora of topological states in ultrathin films made by a prototypical ferroelectric system, depending on the characteristics of these pulses and films. Consequently, these ultrafast electrical pulses in ultra-thin ferroelectrics offer key ingredients for mimicking neuronal and synaptic behaviors, including all-optical devices, and open a new avenue for topological objects to neuromorphic systems.
