Journal ArticleDOI
Generalized bulk–boundary correspondence in non-Hermitian topolectrical circuits
Tobias Helbig,Tobias Hofmann,Stefan Imhof,M. AbdelGhany,Tobias Kiessling,Laurens W. Molenkamp,Ching Hua Lee,Alexander Szameit,Martin Greiter,Ronny Thomale +9 more
TL;DR: In this paper, a non-Hermitian skin effect was observed in a topolectric circuit with respect to the presence of a boundary, and the voltage signal accumulates at the left or right boundary and increases as a function of nodal distance to the current feed.
Journal ArticleDOI
Topological Funneling of Light
Sebastian Weidemann,Mark Kremer,Tobias Helbig,Tobias Hofmann,Alexander Stegmaier,Martin Greiter,Ronny Thomale,Alexander Szameit +7 more
TL;DR: Using a time-dependent photonic lattice in which the topological properties can be controlled, Weidemann et al. show that such a structure can efficiently funnel light to the interface irrespective of the point of incidence on the lattice.
Journal ArticleDOI
Chiral Voltage Propagation and Calibration in a Topolectrical Chern Circuit.
TL;DR: The proposed topolectrical Chern circuit features an admittance bulk gap fully tunable via the resistors used in the INICs, along with a chiral voltage boundary mode reminiscent of the Berry flux monopole present in the admittance band structure.
Journal ArticleDOI
Reciprocal skin effect and its realization in a topolectrical circuit
Tobias Hofmann,Tobias Helbig,Frank Schindler,Frank Schindler,Nora Salgo,Marta Brzezińska,Marta Brzezińska,Martin Greiter,Tobias Kiessling,D. Wolf,Achim Vollhardt,Anton Kabaši,Ching Hua Lee,Ching Hua Lee,Ante Bilušić,Ronny Thomale,Titus Neupert +16 more
TL;DR: The reciprocal skin effect as discussed by the authors describes the conspiracy of non-Hermiticity and non-reciprocity to yield extensive anomalous localization of all eigenmodes in a (quasi) one-dimensional geometry.
