Topological properties in non-Hermitian tetratomic Su-Schrieffer-Heeger lattices
In this paper, we study the topological properties of non-Hermitian Su-Schrieffer-Heeger (SSH) lattices by periodically introducing onsite imaginary potentials in the manner of (iγ_{1}, −iγ_{2}, −iγ_{1}, iγ_{2}), where γ_{1} and γ_{2} are the imaginary-potential strengths. Results show that by chang...
