Summary: We propose a scheme to enhance the phonon blockade effect in a quadratically coupled optomechanical system by introducing a mechanical parametric amplifier (MPA) through a degenerate parametric drive. Both the single-phonon resonant regime and multipath interference regime can achieve phonon blockade due to the optomechanical nonlinearity and MPA. The combination of these two regimes enhances the phonon blockade effect compared to the regime without MPA. Moreover, our scheme shows that the two-time second-order correlation function gradually tends to one without rapid oscillations, suggesting that high time resolution is not necessary in the detection.

Summary: This study introduces a novel metamaterial geometry for multiband transparency in the terahertz domain, utilizing strong near field coupling between toroidal excitation and C-resonators to achieve multiple transparency windows. High Q factor resonances are reported, and the frequency modulation of transparency windows by changing the distance between TSRR and C resonators is demonstrated. The study has the potential to impact the development of terahertz photonic components for next generation devices.

Summary: We propose a scheme to achieve the two-phonon blockade effect in a quadratically coupled optomechanical system and investigate the effects of strongly driving the optical cavity and weakly driving the mechanical resonator. By calculating the correlation function, we study the statistical characteristics of phonons and also consider the influence of thermal noise.

Summary: Electromagnetically induced transparency and absorption have applications in atomic systems, including slow-light generation, while coupled-resonator-induced transparency and absorption serve as their optical analogues. Theoretical and experimental studies on CRIT and CRIA in directly coupled whispering-gallery-mode microresonators provide conditions for observing and predicting transitions between them with changes in coupling strength. The experimental demonstration of transitions between CRIT and CRIA using a microsphere coupled to a sausagelike microresonator offers guidelines for observation.

Summary: This paper presents a complete theory of phonon lasers and emphasizes the importance of the previously ignored optomechanical interaction. The optomechanical interaction is equivalent to a Kerr nonlinear interaction and enhances phonon lasing. Experimental results confirm the validity of the theory and provide new possibilities for manipulating optomechanical phonon lasers.

Summary: This study experimentally demonstrates the phase manipulation of entangled states using a phase-sensitive amplifier based on four-wave mixing, allowing for flexible generation of entanglement with different phase space squeezing orientations. The concise scheme can be expanded to generate multi-parties entangled states on demand.

Summary: This paper presents the observation of a transition from electromagnetically induced transparency (EIT) to absorption (EIA) in a single whispering-gallery-mode (WGM) optical microresonator. By stretching the microresonator, the resonance frequencies of two coupled optical modes are tuned to be the same, resulting in the observed transition from EIT to EIA in the transmission spectra when a fiber taper is moved closer to the microresonator. The special spatial distribution of the optical modes of the microresonator provides a theoretical basis for this observation.

Summary: The study reveals that a polarization mismatch between two indirectly coupled resonators can lead to polarization-induced transparency (PIT), which is distinct from EIT and exhibits a unidirectional feature, providing additional routes for manipulating light flow in optical resonator systems.

Summary: In this paper, a coherent feedback loop scheme is proposed to enhance the magnon-photon-phonon entanglement in cavity magnomechanics. The steady state and dynamical state of the system are proven to form a genuine tripartite entanglement state. Experimental parameters are used to implement the proposal and achieve the tripartite entanglement. The entanglement is significantly improved with coherent feedback and is resistant to environmental thermalization.

Summary: This article reports on a method of inducing a tunable THz lattice in magnetized monolayer graphene through interference of optical beams. By manipulating the optical parameters, the optical properties of the induced lattice can be efficiently tuned, and adjustable effects are observed in far-field diffraction. The research provides a versatile tool for all-optical switching at the few photons level and paves the way for the development of next generation high-speed wireless communication.

Summary: The study demonstrates the active modulation of EIT analog by integrating graphene into a microwave metamaterial for the first time, showing that the EIT peak can be dynamically controlled under a relatively low bias voltage applied on graphene. The continuous tuning of the EIT resonance strength is achieved by variably dampening the dark resonator using graphene.

Summary: We studied the transmission of probe fields in a coupled-cavity system with polaritons and proposed a theoretical framework for realizing a polariton-based photonic transistor. The resonant point, intensity, and group velocity of the probe light passing through the optomechanical device can be effectively controlled by another pump light, depending on the exciton-photon coupling and single-photon coupling. We also discovered an asymmetric Fano resonance in transparency windows under strong exciton-photon coupling, providing exciting possibilities for designing photonic transistors and polariton integrated circuits.

Summary: By studying the quantum interference of incoherent radiation in atomic three-level systems, we have discovered that the exchange of optical vortices can be achieved using a pair of weak laser pulses. We have also found that there are differences in the losses and exchange efficiency between the V-type and A-type atomic-light coupling, depending on whether noise-induced coherence is taken into account.

Summary: We propose a scheme to achieve magnon-induced absorption (MIA) in a two-cavity magnonics system. By manipulating photon and magnon-photon couplings, three interference pathways are established, leading to the conversion from suppression to enhancement on resonance. The analytical results of the probe absorption based on bright and dark modes accurately explain the characteristics of the absorption peaks. Furthermore, similar MIA phenomena are observed in the noise spectral density (NSD) of the microwave cavity, providing a potential method for remote magnon detection using optics.
