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: 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: In this paper, the dissipative-coupling-induced transparency (DCIT) and the enhancement of high-order sidebands in a dissipative photon-magnon coupling system with Kerr nonlinearity are theoretically investigated. It is found that DCIT can be observed under both weak and strong driving fields, and the sidebands can be highly enhanced by selecting the optimized parameters.

Summary: This study demonstrates improved sensitivity of Rydberg electrometry based on electromagnetically induced transparency (EIT) with a ground state repumping laser, which enhances the interaction strength without additional Doppler or power broadening. The nearly doubled EIT amplitude without increased peak width is achieved through this method, showing that similar amplitude increase without repumping field is not possible through simple optimization. The study also identifies photon shot noise of the probe laser as a key limit to detection sensitivity, and shows a nearly 2x improvement in sensitivity with the presence of the repump field.

Summary: We propose a programmable graphene metasurface based on the quantum effect analogue, electromagnetically induced transparency, which enables continuous amplitude and phase tuning of cross-polarized transmission in the terahertz (THz) regime. This programmable scheme allows flexible control over the diffraction angles and focal lengths of the transmitted THz beams, providing new inspirations for THz programmable metasurface devices.

Summary: Recent works in metamaterials and transformation optics have shown exotic properties in open systems, such as perfect absorption/transmission, electromagnetically induced transparency, and cloaking. However, most studies focused on eigenstate properties and paid less attention to the reflection characteristics in the complex frequency plane. In this work, we demonstrate that the indirectly coupled two-magnon system exhibits non-Hermitian eigenmode hybridization and zero-reflection (ZR) states with pure real frequency. The observed perfect-ZR (PZR) state manifests as infinitely narrow reflection dips with infinite group delay discontinuity, and it can be adjusted on or off resonance with the eigenstates, allowing flexible control of absorption and transmission.

Summary: This study introduces both photothermal and rotational effects simultaneously in a single cavity system, proposing a novel scenario. Two double transparency windows are found at two different frequencies simultaneously, and it is investigated that the two transparencies are independent of each other.

Summary: The study explores the influence of cavity field fluctuations on Kerr nonlinearity in an atom-assisted optomechanical system, revealing the generation of new self-Kerr (SK) and cross-Kerr (CK) nonlinearities based on these fluctuations. The nonlinearity features can be enhanced and modified by atom-cavity and optomechanical interactions, providing a potential method for generating novel nonlinear effects.

Summary: We propose a scheme to realize the coherent control of optical soliton propagation and interaction in a three-level Λ-type electromagnetically induced transparency system with the control field being spatially modulated. We show that the spatial perturbation of the control field has no influence on the linear propagation properties and self-phase modulation of the probe field but can produce an equivalent external potential to affect the nonlinear propagation of the probe field. Our results demonstrate the transmission and trapping of optical solitons via external potential, the coherent control of attractive and repulsion interactions of two optical solitons, the design of an XNOR logical operation, and the design of a beam selector based on the coherent control of interaction between three solitons via external potential.

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.

The dynamics of the slime mold is shown to be effective in constructing efficient networks through computer simulations and theoretical analysis. The optimum solution is characterized by minimizing the combined cost of the network and routing demands.

Summary: This study investigates the quantum dynamics of a spin chain that simulates Conway's Game of Life. By solving the time-dependent Schrodinger equation for separable initial states, the evolution of quantum correlations across the lattice is analyzed. Examples of evolutions resulting in entangled chains or oscillating entangling structures are reported and characterized using entanglement and network measures. The quantum patterns exhibit structures that differ significantly from classical ones, even in the dynamics of local observables. A notable example is a structure that behaves as a quantum analog of a blinker, but does not have a classical counterpart.

Summary: This study analyzes the spectral properties of optical photons emitted by solid-state quantum memory and the relationship between stored and retrieved excitations. The results can be applied to optical-to-optical and microwave-to-optical transducers working over a wide range of frequencies. The efficiency of the solid-state quantum transducer depends on the design of the retrieval process in relation to the storage dynamics.

Summary: The analysis of the extended Bose-Hubbard model with quasiperiodic infinite-range interactions reveals that a significant fraction of eigenstates becomes localized as the strength of the global interactions is increased. The behavior scales differently depending on the choice of the thermodynamic limit. The system is asymptotically ergodic by scaling the interaction strength to keep the energy extensive, while the MBL regime appears to be stable with superextensive scaling of the energy, which can be experimentally verified in cavity quantum electrodynamics setups through quench spectroscopy.

Summary: This study investigated the normal-mode spectrum of a trapped ion chain at the symmetry-breaking linear to zigzag transition and at finite temperatures. Although the expected mode softening at the critical point was not observed experimentally, numerical simulations suggest that this is due to the finite temperature of the chain. The study developed an effective analytical model to reproduce the low-frequency spectrum as a function of temperature and close to the transition point, providing insights into the frequency shift of the soft mode and the effect of anharmonic coupling with high-frequency modes.
