Topological defect engineering and PT-symmetry in non-Hermitian electrical circuits
Alexander Stegmaier, Stefan Imhof, Tobias Helbig +14
We employ electric circuit networks to study topological states of matter in non-Hermitian systems enriched by parity-time symmetry and chiral symmetry anti-$\mathca…

Real and imaginary edge states in stacked Floquet honeycomb lattices
Alexander Fritzsche, Bastian Höckendorf, Andreas Alvermann +1
We present a non-Hermitian Floquet model with topological edge states in real and imaginary band gaps. The model utilizes two stacked honeycomb lattices which can be related via fo…
