WebAbstract. Exceptional points (EPs), also known as non-Hermitian degeneracies, have been observed in parity-time symmetric metasurfaces as parity-time symmetry breaking points. However, the parity-time symmetry condition puts constraints on the metasurface parameter space, excluding the full examination of unique properties that stem from an EP. streaming phone to tvWeb22 dec. 2024 · Non-Hermitian systems with parity-time (PT) symmetry reveal rich physics beyond the Hermitian regime.
