Thresholdless dynamical instability in transverse -symmetric scattering systems: The hidden role of bound states in the continuum
Chao Zheng
The stationary scattering properties of transverse parity-time () symmetric systems have been extensively studied, yet their dynamical stability, a prerequisite for a…

Size-dependent dynamical instability of periodic -symmetric scattering systems
Chao Zheng
While periodic -symmetric structures offer a versatile platform for wave tailoring, their scattering responses are typically analyzed using stationary methods that pr…
