Originated by the author in 1998, the field of PT (parity-time) symmetry has become an extremely active and exciting area of research. PT-symmetric quantum and classical systems have theoretical, experimental, and commercial applications, and have been the subject of many journal articles, PhD th...

Here we demonstrate experimentally passive PT-symmetry breaking within the realm of optics. This phase transition leads to a loss induced optical transparency in specially designed pseudo-Hermitian guiding potentials.关键词: physics of elementary particles and fields classical and quantum mechanics, general...
Due to their high degree of flexibility and controllability, gain–loss-balanced optical systems provide a versatile platform to exploit the fundamental nature of the non-Hermitian PT-symmetric quantum mechanics in experiment2. Thus far, a number of PT-symmetry-related phenomena, including spontaneous...
PT-symmetry in Rydberg atoms 鈥Every physical observable in quantum mechanics requires a real spectrum with a Hermitian Hamiltonian, nevertheless, Bender and co-workers claimed that non-Hermitian Hamiltonians can have real spectra under the parity (P) and time (T... Ziauddin,You-Lin Chuang,Ray-...

Here, we experimentally demonstrate single-qubit coherence flow in \({{{\mathcal{P}}}{{{\mathcal{T}}}\)- and \({{{\mathcal{APT}}}\)-symmetric systems using an optical setup. In the symmetry unbroken regime, we observe different periodic oscillations of coherence. Particularly, we...
While realization in quantum systems could be in doubt, several unconventional PT -symmetry related phenomena, such as transition from real-frequency modes to conjugate pair of complex-frequency modes, have been applied in classical photonic systems2–12. Recently, many efforts have been put on ...
