Zusammenfassung: | The exploration of quantum‐inspired symmetries in optical and photonic systems has witnessed immense research interest both fundamentally and technologically in a wide range of subject areas in physics and engineering. One of the principal emerging fields in this context is non‐Hermitian physics based on parity‐time symmetry, originally proposed in the studies pertaining to quantum mechanics and quantum field theory and recently ramified into a diverse set of areas, particularly in optics and photonics. The intriguing physical effects enabled by non‐Hermitian physics and PT symmetry have enhanced significant application prospects and engineering of novel materials. In addition, there has been increasing research interest in many emerging directions beyond optics and photonics. Here, the state‐of‐the art developments in the field of complex non‐Hermitian physics based on PT symmetry in various physical settings are brought together, and key concepts, a background, and a detailed perspective on new emerging directions are described. It can be anticipated that this trendy field of interest will be indispensable in providing new perspectives in maneuvering the flow of light in the diverse physical platforms in optics, photonics, condensed matter, optoelectronics, and beyond, and will offer distinctive application prospects in novel functional materials.
As a quantum‐inspired symmetry paradigm in optical and photonic systems, non‐Hermitian physics based on parity‐time symmetry has gained significant research interest in a wide range of subjects, enabling intriguing physical effects and significant application prospects. The state‐of‐the‐art developments in this trendy field in various physical settings are discussed, and key concepts, background, and a detailed perspective on new emerging directions are also provided. |
