Transverse spin texture in optical non-Hermitian skin modes
Naoki Ichiji, Issei Takeda, Taiki Yoda +3
In structured electromagnetic fields, polarization textures are often closely linked to the spatial variation of the energy flow. However, this familiar picture has been establishe…

Observation of non-Hermitian point gap in photonic crystals
Yuto Moritake, Nozomi Ogawa, Issei Takeda +7
Non-Hermitian point gap (NHPG) is a unique phenomenon in non-Hermitian systems and induces non-Hermitian skin effect (NHSE). In photonic crystals, NHPG and the NHSE have previously…

Propagation and circulating modes of reciprocal non-Hermitian skin effect
Issei Takeda, Taiki Yoda, Yuto Moritake +2
The non-Hermitian skin effect (NHSE) is a novel localization phenomenon, in which all bulk states in a non-Hermitian system under certain conditions are localized at the edge of th…
