Non-Hermitian chiral degeneracy of gated graphene metasurfaces
Soojeong Baek, Sang Hyun Park, Donghak Oh +9
Non-Hermitian degeneracies, also known as exceptional points (EPs), have been the focus of much attention due to their singular eigenvalue surface structure. Nevertheless, as perta…

Resonance-enhanced spectral funneling in Fabry-Perot resonators with a temporal boundary mirror
Kanghee Lee, Junho Park, Seojoo Lee +4
A temporal boundary refers to a specific time at which the properties of an optical medium are abruptly changed. When light interacts with the temporal boundary, its spectral conte…

Observation of an exceptional point in a non-Hermitian metasurface
Sang Hyun Park, Sung-Gyu Lee, Taewoo Ha +6
Exceptional points, also known as non-Hermitian degeneracies, have been observed in parity-time symmetric metasurfaces as the parity-time symmetry breaking point. However, the pari…
