The topological Faraday effect cannot be observed in a realistic sample
Christian Berger, Florian Bayer, Laurens W. Molenkamp +1
A striking feature of 3 dimensional (3D) topological insulators (TIs) is the theoretically expected topological magneto-electric (TME) effect, which gives rise to additional terms…
Topolectrical circuit realization of topological corner modes
Stefan Imhof, Christian Berger, Florian Bayer +8
Quantized electric quadrupole insulators have recently been proposed as novel quantum states of matter in two spatial dimensions. Gapped otherwise, they can feature zero-dimensiona…
Topolectrical circuits
Ching Hua Lee, Stefan Imhof, Christian Berger +5
Invented by Alessandro Volta and Félix Savary in the early 19th century, circuits consisting of resistor, inductor and capacitor (RLC) components are omnipresent in modern technolo…
