The notion of non-Hermitian optics and photonics rooted in quantum mechanics and
photonic systems has recently attracted considerable attention ushering in tremendous …

The exploration of quantum‐inspired symmetries in optical and photonic systems has
witnessed immense research interest both fundamentally and technologically in a wide …

Non-Hermiticity enriches topological phases beyond the existing Hermitian framework.
Whereas their unusual features with no Hermitian counterparts were extensively explored, a …

The permutational invariance of identical two-level systems allows for an exponential
reduction in the computational resources required to study the Lindblad dynamics of …

A non-Hermitian extension of a Chern insulator and its bulk-boundary correspondence are
investigated. It is shown that in addition to the robust chiral edge states that reflect the …

We investigate a topological superconducting wire with balanced gain and loss that is
effectively described by the non-Hermitian Kitaev/Majorana chain with parity-time symmetry …

We propose to realize the pseudo-Hermiticity in a cavity magnonics system consisting of the
Kittel modes in two small yttrium iron garnet spheres coupled to a microwave cavity mode …

Exceptional points (EPs) are exotic degeneracies of non-Hermitian systems, where the
eigenvalues and the corresponding eigenvectors simultaneously coalesce in parameter …

Recently, apparent nonphysical implications of non-Hermitian quantum mechanics (NHQM)
have been discussed in the literature. In particular, the apparent violation of the no-signaling …

Higher-order exceptional points (EPs), resulting from non-Hermitian degeneracies, have
shown greater advantages in sensitive enhancement than second-order EPs (EP2s) …
