Abstract Epsilon‐near‐zero (ENZ) photonics is the study of light–matter interactions in the
presence of structures with near‐zero permittivity and has been emerging as an important …

With its unique and exclusive linear and nonlinear optical characteristics, epsilon-near-zero
(ENZ) photonics has drawn a tremendous amount of attention in the recent decade in the …

We proposed and demonstrated that PT symmetric metamaterials could be used to achieve
enhanced spin Hall effect (SHE) of light. We find that when laser mode is excited in PT …

A theoretically and numerically photonic crystal structure with parity-time symmetry is
investigated to realize the design of a biomedical sensor for biosensing applications. The …

Geometrical symmetry plays a significant role in implementing robust, symmetry-protected,
bound states in the continuum (BICs). However, this benefit is only theoretical in many cases …

The resonance energy transfer and entanglement between two-level quantum emitters are
typically limited to sub-wavelength distances due to the inherently short-range nature of the …

Nonreciprocal transmission forms the basic operation mechanism of optical diodes and
isolators and requires the tantalizing task of breaking the Lorentz reciprocity law. In this …

Goos-Hänchen (GH) effect is a fundamental phenomenon in optics. Here we demonstrate
theoretically that the surface modes at Parity-time (PT) symmetric interfaces, can induce a …

Over the past decade, parity-time (PT)-symmetric Hamiltonians have been experimentally
realized in classical, optical settings with balanced gain and loss, or in quantum systems …

The intriguing physics of exceptional points (EPs) and spectral singularities in open (non-
Hermitian) active photonic systems has recently sparked increased interest among the …
