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…
Nonlinearity-induced photonic topological insulator
Lukas J. Maczewsky, Matthias Heinrich, Mark Kremer +8
The hallmark feature of topological insulators renders edge transport virtually impervious to scattering at defects and lattice disorder. In our work, we experimentally demonstrate…
Non-Hermitian Anderson Transport
Sebastian Weidemann, Mark Kremer, Stefano Longhi +1
Andersons groundbreaking discovery that the presence of stochastic imperfections in a crystal may result in a sudden breakdown of conductivity revolutionized our understanding of d…
Experimental observation of Aharonov-Bohm caging using orbital angular momentum modes in optical waveguides
C. Jörg, G. Queraltó, M. Kremer +6
The discovery of artificial gauge fields, controlling the dynamics of uncharged particles that otherwise elude the influence of standard electric or magnetic fields, has revolution…
Efficient Light Funneling based on the non-Hermitian Skin Effect
Sebastian Weidemann, Mark Kremer, Tobias Helbig +5
In the last two decades, the ubiquitous effect of dissipation has proven to entail astonishing non-Hermitian features, rather than just being an inescapable nuisance. As an alterna…
