The exploration of quantum‐inspired symmetries in optical and photonic systems has
witnessed immense research interest both fundamentally and technologically in a wide …

We propose how to achieve quantum nonreciprocity via unconventional photon blockade
(UPB) in a compound device consisting of an optical harmonic resonator and a spinning …

We theoretically study the role of the exceptional point (EP) in a non-Hermitian cavity
magnomechanical (CMM) system, with a tunable dissipative magnon-photon coupling. We …

Loss and noise are usually undesirable in electronics and optics, which are generally
mitigated by separate ways in the cost of bulkiness and complexity. Recent studies of non …

Bound states in the continuum (BICs) present a unique solution for eliminating radiation
loss. So far, most reported BICs are observed in transmission spectra, with only a few …

Loss-induced transparency (LIT), featuring the revival of optical intensity by adding loss, has
been demonstrated in classical optics. However, a fundamental question has remained …

We study the photon blockade at exceptional points for a non-Hermitian optomechanical
system coupled to the driven whispering-gallery-mode microresonator with two …

Induced transparency, an interference effect due to mode coupling, has attracted significant
research interest. The first discovered and most striking type of induced transparency plays …

Non-Hermitian systems with anti-parity-time (a PT) symmetry have revealed rich physics
beyond conventional systems. Here, we study optomechanics in an a PT-symmetric …

Here, a scheme for a controllable nonreciprocal phonon laser is proposed in a hybrid
photonic molecule system consisting of a whispering-gallery mode (WGM) optomechanical …
