Synthetic-reflectionless-mode exceptional degeneracies via emergent local symmetries
The authors demonstrate the emergence of exceptional points that arise when a local PT symmetry in the synthetic frequency space of a driven system governs an auxiliary operator that encodes reflectionless boundary conditions of the Floquet scattering problem. The underlying framework establishes a foundation for controlled wavefront shaping in synthetic spaces of periodically time-modulated systems.
