We further demonstrate that ECs can be observed in prototypical non-Hermitian photonic crystals. Our results combine the effect of non-Hermitian spatiotemporal symmetry and topology to pave the way for understanding and manipulating the morphology of ELs in non-Hermitian crystalline systems.#Exceptional...
The spontaneous breaking of parity-time (PT) symmetry yields rich critical behavior in non-Hermitian systems, and has stimulated much interest, albeit most previous studies were performed within the single-particle or mean-field framework. Here, by studying the collective excitations of a Fermi super...
It has subsequently been experimentally realized on versatile platforms including photonics and nanophotonics12,13,14,15, plasmonics16 and quantum optics17 and in the context of parity–time symmetry and nonlinear non-Hermitian phenomena18,19. Fig. 2: Demonstration of the A-SubSy-protected ...
In the twentieth century, the global level and properties of Lie groups and differential geometry became the most prominent. This really was a fundamental feature of mathematics, and especially of geometry and topology, in the twentieth century. A major development realized by the work of many ...
While most of the researches are carried out in closed systems, the open systems which are described by Non-Hermitian Hamiltonian have widespread applications as well [32], [33]. Especially, the interplay between non-Hermiticity and topology has attracted tremendous attention [34], [35], [36]...

Nearly one century after the birth of quantum mechanics, parity–time symmetry is revolutionizing and extending quantum theories to include a unique family of non-Hermitian Hamiltonians. While conceptually striking, experimental demonstration of parity–time symmetry remains unexplored in quantum electronic ...
