Critical System Size for the Recovery of Topological Zero Modes in Finite Non‐Hermitian Systems

Annalen der Physik, Volume 537, Issue 12, December 2025.
A generalized non‐Hermitian SSH model on a topolectrical circuit reveals size‐dependent topological zero modes. Non‐Hermiticity enables exact zero‐admittance edge states at a critical system size, tunable via asymmetric coupling and gain/loss. Large impedance peaks signal these modes, offering insights for designing robust topological devices with ...
