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

Non-Hermitian systems can exhibit unconventional spectral singularities called exceptional
points (EPs). Various EP sensors have been fabricated in recent years, showing strong …

The chaotic light source is one of the most crucial foundations in optical physics studies and
photonic devices. The microcavity provides the predominant solution of compact chaotic …

Hermitian Hamiltonians with time-periodic coefficients can be analyzed via Floquet theory,
and have been extensively used for engineering Floquet Hamiltonians in standard quantum …

In the paper is shown that the metal is a more active partner in Schottky diodes (SD) based
on metal-semiconductor contact (MSC) from the series of semiconductor devices. It is shown …

Different from the Hermitian case, non-Hermitian (NH) systems have novel properties and
strongly relate to open and dissipative quantum systems. In this work, we investigate how to …

Existence of PT symmetric regime in a system of two semiconductor lasers coupled face to
face is being reported. The coupling involves the field of one laser coupled to the field of the …

In this work, the optical properties and dynamical behaviors of the optical parametric
oscillation under the anti Parity-Time (anti-PT) symmetry are studied. The non-Hermitian …

The present paper illustrates the realization of an atom-optomechanical system where an
atomic ensemble is confined in a ring optomechanical cavity consisting of a fixed mirror and …

Hermiticity is the fundamental property of the physical systems, for which it should obey the
laws of energy conservation and time-reversal symmetry. Parity-time symmetry is introduced …
