Reciprocal skin effect and its realization in a topolectrical circuit
Tobias Hofmann, Tobias Helbig, Frank Schindler +11
A system is non-Hermitian when it exchanges energy with its environment and non-reciprocal when it behaves differently upon the interchange of input and response. Within the field…
Observation of bulk boundary correspondence breakdown in topolectrical circuits
Tobias Helbig, Tobias Hofmann, Stefan Imhof +7
The study of the laws of nature has traditionally been pursued in the limit of isolated systems, where energy is conserved. This is not always a valid approximation, however, as th…
Active topolectrical circuits
Tejas Kotwal, Fischer Moseley, Alexander Stegmaier +6
The transfer of topological concepts from the quantum world to classical mechanical and electronic systems has opened fundamentally new approaches to protected information transmis…
High-resolution Resonance Spin-flip Raman Spectroscopy of Pairs of Manganese Ions in CdTe
Cherbunin R. V., Litviak V. M., Ryzhov I. I. +8
We report the observation of tens of minor lines of the combinational spin-flip Raman scattering in a CdTe:Mn quantum well by means of the high-resolution optical spectroscopy. Cla…
