Cavity optomechanics deals with the radiation pressure induced interaction between
photons and mechanical motion in a cavity. It has promising applications in quantum …

In the past few decades, many works have been devoted to the study of exceptional points
(EPs), ie, exotic degeneracies of non-Hermitian systems. The usual approach in those …

A two-mode optical parity-time (PT) symmetric system, with gain and damping, described by
a quantum quadratic Hamiltonian with additional small Kerr-like nonlinear terms, is analyzed …

Almost a decade ago, physicists encountered a strange quantum phenomenon that predicts
an unusual death of entanglement, under the influence of a local noisy environment, known …

In the presence of arbitrary three-dimensional linear media with material loss and
amplification, we present an electromagnetic field quantization scheme for quasinormal …

We study the dynamics of correlations in a paradigmatic setup to observe PT-symmetric
physics: a pair of coupled oscillators, one subject to a gain one to a loss. Starting from a …

We theoretically investigate PT symmetry, induced mechanical lasing, and force sensing in
an optically levitated nanoparticle with coupled oscillation modes. The coupling in the …

Gain saturation is ubiquitous but has not been fully explored in the newly developed field of
non-Hermitian optics. On the other hand, the nonclassical properties of light are highly …

We study the significance of Photon/Phonons bunching and antibunching on the dynamics
of the quantum entanglement in the presence of coupled P T-symmetry systems with …

We show that the loss of nonclassicality (including quantum entanglement) cannot be
compensated by the (incoherent) amplification of PT-symmetric systems. We address this …
