The Transmission Properties and Dynamical Characterization Driven by the Flat Bands in a Non‐Hermitian Dimerized Lattice

ABSTRACT A method of Fourier transform engineering is demonstrated to constructing flat bands in a two‐band model. By introducing a momentum‐dependent pseudo‐‐symmetry potential into a generalized Su–Schrieffer–Heeger model, we generate two momentum‐independent flat bands. The co...
