Topological Edge State Nucleation in Frequency Space and its Realization with Floquet Electrical Circuits
Alexander Stegmaier, Alexander Fritzsche, Riccardo Sorbello +11
We build Floquet-driven capactive circuit networks to realize topological states of matter in the frequency domain. We find the Floquet circuit network equations of motion to revea…
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…
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…
