Unveiling the Self-Orthogonality at Exceptional Points in Driven -Symmetric Systems
Alexander Fritzsche, Riccardo Sorbello, Ronny Thomale +1
We explore the effect of self-orthogonality at exceptional points (EPs) in non-Hermitian Parity-Time-symmetric systems. Using a driven three-band lattice model, we show that the Ra…

Simulating Holographic Conformal Field Theories on Hyperbolic Lattices
Santanu Dey, Anffany Chen, Pablo Basteiro +10
We demonstrate how table-top settings combining hyperbolic lattices with nonlinear dynamics universally encode aspects of the bulk-boundary-correspondence between gravity in anti-d…

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…
