Abstract: Most existing non-Hermitian topological systems derive their nontrivial topology from Hermitian factors. Here, the authors report on the experimental observation of acoustic topological edge states induced solely by non-Hermiticity. They show that non-Hermiticity is able… read more here.

Abstract: We reveal a one-dimensional topological insulating phase induced solely by gain and loss control in non-Hermitian optical lattices. The system comprises units of four uniformly coupled cavities, where the successive two have loss; the others… read more here.
