Realizing efficient topological temporal pumping in electrical circuits

Alexander Stegmaier, Hauke Brand, Stefan Imhof +11

Quantized adiabatic transport can occur when a system is slowly modulated over time. In most realizations however, the efficiency of such transport is reduced by unwanted dissipati…

Observation of cnoidal wave localization in non-linear topolectric circuits

Hendrik Hohmann, Tobias Hofmann, Tobias Helbig +12

We observe a localized cnoidal (LCn) state in an electric circuit network. Its formation derives from the interplay of non-linearity and the topology inherent to a Su-Schrieffer-He…

Hyperbolic Matter in Electrical Circuits with Tunable Complex Phases

Anffany Chen, Hauke Brand, Tobias Helbig +11

Curved spaces play a fundamental role in many areas of modern physics, from cosmological length scales to subatomic structures related to quantum information and quantum gravity. I…

Simulating hyperbolic space on a circuit board

Patrick M. Lenggenhager, Alexander Stegmaier, Lavi K. Upreti +12

The Laplace operator encodes the behavior of physical systems at vastly different scales, describing heat flow, fluids, as well as electric, gravitational, and quantum fields. A ke…

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…

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…

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…

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…
