In a generalized non-Hermitian Rice-Mele model, next-nearest-neighbor hopping leaves exceptional-point loci unchanged under periodic boundaries but shifts existing points and creates new ones under open boundaries, producing size-dependent degeneracies and a boundary-specific topological gap-closing

Non-Hermitian Crystalline Braid Topology from Hermitian Projection: A Zero-Mode Resonance Mechanism
Non-Hermitian braid topology emerges from zero-mode resonant projection of a Hermitian parent lattice, with the braid count identified with the quantized complex Berry phase under conjugated pseudo-Hermiticity induced by embedding parity.
