We study the construction of programable integrated circuits with the help of disordered Chern insulators (CIs) in this letter. Specifically, the schemes for low dissipation logic devices and connecting wires are proposed. We use the external-gate-induced step voltage to construct spatially adjustable channels, where these channels take the place of the conventional wires. Our numerical calculation manifests that the external gates can be adopted to program the arbitrary number of wires ($n$-to-$m$ connections). We find that their electron transport is dissipationless and robust against gate voltage fluctuation and disorder strength. Furthermore, seven basic logic gates distinct from the conventional structures are proposed. Our proposal has potential applications in low power integrated circuits and enlightens the building of integrated circuits in topological materials.
In this Letter, we study an Anderson-localization-induced quantized transport in disordered Chern insulators (CIs). By investigating the disordered CIs with a step potential, we find that the chiral interface states emerge along the interfaces of the
Even though no local order parameter in the sense of the Landau theory exists for topological quantum phase transitions in Chern insulators, the highly non-local Berry curvature exhibits critical behavior near a quantum critical point. We investigate
In disordered two dimensional Chern insulators, a single bulk extended mode is predicted to exist per band, up to a critical disorder strength; all the other bulk modes are localized. This behavior contrasts strongly with topologically trivial two-di
Chern insulator or quantum anomalous Hall state is a topological state with integer Hall conductivity but in absence of Landau level. It had been well established on various two-dimensional lattices with periodic structure. Here, we report similar Ch
We elucidate the mechanism by which a Mott insulator transforms into a non-Fermi liquid metal upon increasing disorder at half filling. By correlating maps of the local density of states, the local magnetization and the local bond conductivity, we fi
