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

We revisit the fate of the skin modes in many-body non-Hermitian fermionic systems.
Contrary to the single-particle case, the many-body ground state cannot exhibit an …

Using the Maxwell-Bloch equations for resonantly absorbing and amplifying media, we
study the temporal dynamics of light propagation through the PT-symmetric structures with …

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 …

Interference of transmitted and received signals hinders the simultaneous functionality of a
conventional optical antenna as a transmitter and receiver which is required for full-duplex …

The large cross sections and strong confinement provided by the plasmon resonances of
metallic nanostructures make these systems an ideal platform to implement nanoantennas …

Metallic nanostructures endowed with optical gain are promising building blocks for the
development of active nanophotonic devices with enhanced optical responses as well as for …

The nonreciprocal properties of coupled nanocavities incorporating a gain medium were
investigated. The proposed coupled nanocavities can be considered as a photonic non …

Gain saturation is ubiquitous but has not been fully explored in the newly developed field of
non-Hermitian optics. On the other hand, the nonclassical properties of light are highly …

We study theoretically an optical cavity and a parity-time (PT)-symmetric pair of mechanical
resonators, where all oscillators are pairwise coupled, forming an optomechanical system …
