Topological invariant and anomalous edge modes of strongly nonlinear systems

HIGHLIGHTS

• who: Di Zhou from the Beijing Institute, China have published the paper: Topological invariant and anomalous edge modes of strongly nonlinear systems, in the Journal: NATURE COMMUNICATIONS NATURE COMMUNICATIONS
• what: In SecIV, the authors propose an electrical circuit as one of the classical systems that yield Eq . The ansatz in Eq correctly states the periodicity of nonlinear bulk modes based on the following reasons. Due to the symmetry constraints of the nonlinear motion equations, the authors demonstrate that all nonlinear bulk states are marginally stable within Floquet analysis64,68,69 (see SI. Now the authors . . .
