The photon statistics emitted by a large variety of light‐matter systems under weak coherent
driving can be understood, to lowest order in the driving, in the framework of an admixture of …

In this paper, we show that nonreciprocal unconventional photon blockade can be observed
in a spinning cavity immersed in a degenerate optical parametric amplifier (OPA) driven by …

We investigate nonreciprocal photon correlations in coupled microring resonators with
directional quantum squeezing (quantum parametric amplification). We show that the …

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

We briefly review the ideas that have shaped modern optics and have led to various
applications of light ranging from spectroscopy to astrophysics, and street lights to quantum …

We study multiphoton blockade and photon-induced tunneling effects in the two-photon
Jaynes-Cummings model, where a single-mode cavity field and a two-level atom are …

We study the behaviour of the second-order correlation function in a double-cavity
optomechanical system, and a degenerate optical parametric amplifier is placed in each …

Nonreciprocal devices, allowing to manipulate one‐way signals, are crucial to quantum
information processing and quantum networks. Here a nonlinear cavity‐magnon system is …

We propose how to realize nonreciprocity for a weak input optical field via nonlinearity and
synthetic magnetism. We show that the photons transmitted from a linear cavity to a …

The photon blockade based on weak nonlinearities is called unconventional photon
blockade. The studies of the unconventional photon blockade in recent decades are all …
