Chiral voltage propagation in a self-calibrated topolectrical Chern circuit
Tobias Hofmann, Tobias Helbig, Ching Hua Lee +2
We propose an electric circuit array with topologically protected uni-directional voltage modes at its boundary. Instead of external bias fields or floquet engineering, we employ n…

Band structure engineering and reconstruction in electric circuit networks
Tobias Helbig, Tobias Hofmann, Ching Hua Lee +4
We develop an approach to design, engineer, and measure band structures in a synthetic crystal composed of electric circuit elements. Starting from the nodal analysis of a circuit…
