Explorations of symmetry and topology have led to important breakthroughs in quantum optics, but much richer behaviors arise from the non-Hermitian nature of light-matter interactions. A high-reflectivity, non-Hermitian optical mirror can be realized by
Exceptional points (EPs) arising in non-Hermitian systems have led to a variety of intriguing wave phenomena, and have been attracting increased interest in various physical platforms. In this Review, we highlight the latest fundamental advances in the context of EPs in various nanoscale systems, ...
In the past few years, concepts from non-Hermitian (NH) physics, originally developed within the context of quantum field theories, have been successfully deployed over a wide range of physical settings where wave dynamics are known to play a key role. In optics, a special class of NH ...
The notion of non-Hermitian optics and photonics rooted in quantum mechanics and photonic systems has recently attracted considerable attention ushering in tremendous progress on theoretical foundations and photonic applications, benefiting from the flexibility of photonic platforms. In this review, we first...

Heralded magnetism in non-Hermitian atomic systems Quantum phase transitions are usually studied in terms of Hermitian Hamiltonians. However, cold-atom experiments are intrinsically non-Hermitian due to spo... TE Lee,CK Chan - 《Physical Review X》 被引量: 6发表: 2014年 Trajectory phase transitio...
A generalization of the theory of geometric optics in plasmas where the local dielectric tensor is not quite Hermitian is presented. It is shown that for g... L Friedland,IB Bernstein - 《Physical Review A》 被引量: 37发表: 1980年 Generalized effective Hamiltonian for graphene under nonuniform...
However, the demonstration of non-Hermitian phenomenon that is quantum in nature has remained elusive. Here, we predict the quantum non-Hermitian phenomena, the fractional quantum Zeno (FQZ) effect and FQZ-induced photon antibunching [1]. We consider a quantum optics platform with reservoir ...
We study the Landau–Zener problem for a decaying two-level system described by a non-Hermitian Hamiltonian, depending analytically on time. Use of a... R Schilling,M Vogelsberger,DA Garanin - 《Journal of Physics.a.mathematical & General A Europhysics Journal》 被引量: 0发表: 2006年 Non...
