Taking the Haldane model as the research system, we extend the current study of topoelectrical circuits modulating interactions and design and construct a general method to modulate the on-site potential energy of the tight-binding model. In this method, efforts are made to achieve the interface state modulation, including changes in the on-site potential energy of the Haldane model, which involves the change in overall on-site potential energy, the application of different on-site potential energies on the two atoms of the honeycomb lattice, and the adjustment to the on-site potential energy of boundary atoms, and in particular, the development of the corresponding design scheme for circuit experiments. The method provides a new idea for further control and utilization of interface states.
