Secondly, the … WebThe non-Hermiticity greatly affects the topological property of the Lieb lattice. When the non-Hermitian term is introduced, the gapped regions shrink and the gapless regions appear; a typical feature is the exis-tence of the EPs.

WebApr 1, 2016 · We show that the bulk-boundary correspondence for topological insulators can be modified in the presence of non-Hermiticity. We consider a one-dimensional tight-binding model with gain and loss as well as long-range hopping. The system is described by a non-Hermitian Hamiltonian that encircles an exceptional point in momentum space. total image photography grayslake north
