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…

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…
