Summary: Through investigating the cavity optomechanical system, it is found that optomechanically induced transparency phenomena can be observed under different driving conditions. The phenomena are influenced by the number of atoms, coupling, and decay rate. Increased number of atoms widens the induced transparency window and enhances its depth.

Summary: The study found that multiple optomechanically induced transparency can be observed in a two-cavity optomechanical system at the probe frequency, and the number and width of transparent windows can be tuned by classical driving power. The distance between the two outermost transparency windows shows a linear relationship with parameters P-l and lambda, showing the feasibility of controlling multipartite induced transparency for quantum networks with photonic and phononic circuits.

Summary: This theoretical study explores how to achieve ultraslow and ultrafast light in an optomechanical system, based on the ideal optomechanically induced transparency. The abnormal transparency window with very steep dispersion allows for easy achievement of ultraslow light, while tuning coupling strength and decay rates enable the attainment of ultrafast light at the transparency window.

Summary: In this study, we investigate controllable optical responses in a previously unstudied two-cavity optomechanical system, focusing on perfect optomechanically induced transparency (OMIT). The findings demonstrate that perfect OMIT can still occur even with high mechanical damping rate, and it enables the achievement of long-lived slow light in the transparent window. Furthermore, we discover that the conversion between perfect OMIT and optomechanically induced absorption can be easily accomplished by adjusting the driving field strength of the second cavity. These results are believed to have implications for controlling optical transmission in modern optical networks.

Summary: We theoretically investigate an optomechanical system consisting of an optical cavity and a PT-symmetric pair of mechanical resonators, where both gain and feedback are present. By breaking time-reversal symmetry and introducing a static synthetic gauge field through loop coupling phase, we demonstrate the controllable transmission amplitude and group delay for both single and double OMT phenomena within a PT-symmetric system.

Summary: We investigate the realization of optomechanically induced gain in a hybrid optomechanical system with an interacting Bose-Einstein condensate trapped inside an optical lattice generated by an external coupling laser tuned to the red sideband of the cavity. The system behaves as an optical transistor, amplifying weak input optical signals considerably in the cavity output if in the unresolved sideband regime. Controlling the s-wave scattering frequency allows the system to switch from the resolved to unresolved sideband regime and significantly enhance system gain.

Summary: The study shows that optomechanically induced transparency can be observed from the output field in a non-Markovian regime, and the location of the absorption peak can serve as an indicator of the strength of the non-Markovian effect. The method developed in this study could potentially be utilized to measure the strength of system-environment coupling.

Summary: This theoretical study investigates the influences of thermal and optomechanical effects on the formation of optical frequency comb (OFC) in whispering gallery-mode (WGM) microcavities. The results show that the thermal effects cause a redshift in the cutoff order and center frequency of OFC, which can be tuned by varying the power and detuning of the pump field.

Summary: In this study, a method to achieve an electromagnetically induced transparency (EIT)-like effect in a whispering gallery mode resonator (WGMR) was proposed and experimentally validated in a lithium niobate (LN) device. The method utilized the electro-optic and inverse piezoelectric effects of LN to tune two modes of the LN WGMR at different rates, resulting in EIT-like resonance lineshapes. The electric field applied to the LN WGMR allowed precise control of the dynamic behavior of the EIT-like phenomenon. The proposed method and demonstrated devices offer potential applications in light storage, quantum information processing, and enhanced sensing techniques.

Summary: We have studied the tunable multicolor optomechanically induced transparency through an electro-optical hybrid system. The results show that under different coupling strengths, the system exhibits an increase in optomechanical induced transparency. The presence of charged mechanical resonators and atoms increases the number of transparency windows, and the transparency phenomena are strongly influenced by the coupling strength between the various components.

Summary: We investigate the tunable double optomechanically induced transparency and slow/fast phenomena in a hybrid electro-optomechanical system. The double transparency phenomenon is strongly influenced by the parametric gain of optical parametric amplifier (OPA) and Coulomb interaction between mechanical oscillators. Furthermore, our approach provides flexibility in controlling double induced transparency and has potential applications in optical information storage and communication.

Summary: The low-energy, long-lived isomer in Th-229 has inspired physicists to explore multidisciplinary research and to develop a highly precise nuclear clock to test fundamental physics principles. In addition, plans are in place to use the nuclear clock for searches of variations in electromagnetic and strong coupling constants, as well as for dark matter studies.

Summary: The enhancement of x-ray-matter interaction by guiding and focusing radiation from x-ray free electron lasers is investigated theoretically. It is shown that elliptical waveguides using a cladding material with a high atomic number can maintain an x-ray intensity of up to three orders of magnitude larger than in free space. This feature can be used to place a nuclear sample in the waveguide focal area and drive nuclear Mossbauer transitions up to transient nuclear population inversion.

Summary: This study theoretically investigates the population of the 8 eV Th-229m isomer through coherent x-ray pulses in the second nuclear excited state at 29.19 keV. Two nuclear coherent population transfer schemes, using stimulated Raman adiabatic passage and successive pi pulses, are focused on. Numerical results indicate that the Gamma Factory approach is the most promising scenario for efficient isomer population. The study also provides theoretically predicted values for nuclear transition probabilities and discusses them in relation to recent experiments.

Summary: We experimentally observed a type of accumulative nonlinear attenuation and distortion of slow light, known as Rydberg polaritons. The observed effect cannot be explained by the dipole-dipole interaction alone between the Rydberg atoms. We attribute this effect to the transition of atoms between bright and dark Rydberg states. Three experiments were conducted to verify this hypothesis and measure the decay rate between the states. The experimental data were consistent with the theoretical predictions based on the model.

Summary: Collective effects in the interaction of light with ensembles of identical scatterers are important in physics. A formalism based on the Green's-function method has been developed to model the linear response of inhomogeneous ensembles in one-dimensional waveguides. The collective spectrum formula exhibits deviations from the expected uniform frequency shift and broadening of two-level systems.
