Antiparity-Time Symmetry in Passive Nanophotonics
Antiparity-Time Symmetry in Passive Nanophotonics
Parity-time (PT) symmetry in non-Hermitian optical systems promises distinct optical effects and applications not found in conservative optics. Its counterpart, anti-PT symmetry, subscribes another class of intriguing optical phenomena and implies complementary techniques for exotic light manipulation. Despite exciting progress, so far, anti-PT symmetry has only been realized in bulky …
