(Color online) Schematic diagram of neuromorphic computing with ferroelectric Chern insulators. (a) Topologically protected edge states in magic-angle twisted bilayer graphene with spontaneous ferroelectricity. Delicately controlled back gate voltage pulse (Vbg) can change the ferroelectric polarization (Pr), enabling selective and non-volatile switching between Chern insulating states with distinct Chern numbers. (b) Schematic of neuromorphic computing with ferroelectric Chern insulators. The weights of the trained kernel are distributed on the quantized resistance values corresponding to these topological edge states, facilitating robust and efficient computation. The figure is provided courtesy of Prof. Feng Miao.
