Quantum Geometry in Hyperbolic Band Theory
Ahmed Adel Mahmoud, Riccardo Sorbello, Ronny Thomale +1
Hyperbolic band theory (HBT) has recently unveiled a wealth of exotic physical phenomena in negatively curved spaces. Concurrently, the quantum metric has emerged as a fundamental…
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…
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…
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…
