Observation of perfectly-chiral exceptional point via bound state in the continuum
Chirality is one of the fundamentals of nature with strong ties to asymmetry. In wave physics,
it is conventionally characterized by asymmetric scattering of circularly polarized waves but …

Non-Hermitian optics in atomic systems
A wide class of non-Hermitian Hamiltonians can possess entirely real eigenvalues when
they have parity-time (PT) symmetric potentials. Recently, this family of non-Hermitian …

Elliptical and rectangular solitons in media with competing cubic–quintic nonlinearities
We demonstrate two new types of non-circularly-symmetric solitons, the elliptical and
rectangular solitons, which can be sustained by the cubic–quintic nonlinearity in the …
