The results show that the system can exhibit single or double OMIT effect by adjusting the external force, and slow-fast light conversion is possible by controlling the external force.

Summary: We investigate the optical behavior of a single Laguerre-Gaussian cavity optomechanical system, consisting of two mechanically rotating mirrors. We explore the effects of various physical parameters on the double optomechanically induced transparency (OMIT) and explain the underlying physical mechanism. We demonstrate that the double-OMIT phenomena is a result of the orbital angular momentum and is produced using a single Laguerre-Gaussian cavity optomechanical system.

Summary: We have developed a novel architecture for microwave cavity optomechanics at room temperature, using a 3D microwave re-entrant cavity and a compliant membrane. By resolving the thermomechanical motion of the membrane, we observed optomechanically induced transparency/absorption for the first time in a microwave optomechanical system operated at room temperature. Single-photon coupling rate (g0) was extracted through four independent measurement techniques, providing a full characterization of the proposed cavity optomechanical system.

Summary: In this paper, a theoretical scheme is proposed to tune both the range and interval of high-order sidebands in a coupled double-cavity optomechanical system. By driving the system with control field, probe field, and pump field, the sideband range can be effectively enlarged by adjusting parameters. The output spectrum includes integer-order sidebands, fraction-order sidebands, and sum and difference sidebands, with the sideband interval controlled by increasing the pump amplitude and m value.

Summary: This study proposes a method to achieve ground-state cooling of the magnomechanical resonator in a cavity magnomechanical system.

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: We report on the electromagnetically induced transparency cooling of Ca-40(+) to sympathetically cool the three-dimensional secular modes of motion in a Ca-40(+)-Al-27(+) two-ion pair near ground state, achieving simultaneous ground state cooling across all radial and axial modes in a broad frequency space. The cooling time is less than 1 ms. This study is crucial for reducing uncertainties in the time dilation shift and uptime ratio in Al-27(+) optical clocks, and for enabling high-fidelity quantum simulations and quantum information processing with trapped ions.

Summary: Based on experimental and theoretical methods, the NO selective catalytic oxidation process over a-MnO2 (110) surface was proposed. The results showed that lattice oxygen served as the active site for NO oxidation, and the second layer oxygen atoms were the most active and stable sites. NO oxidation over the a-MnO2 (110) surface primarily followed the route of O = N-O-O-N = O formation.

Summary: In this article, we study the enhanced sensing of optomechanically induced nonlinearity (OMIN) in a cavity-waveguide coupled system. By introducing weak waveguide-mediated coherent coupling, we find a strong bistable response of the cavity intensity to the OMIN near the cavity resonance. This enhanced sensitivity, measured by an enhancement factor, is resistant to cavity decay and fluctuations in the cavity-waveguide detuning.

Summary: The application of frequency-dependent squeezed vacuum can improve the force sensitivity of an optomechanical interferometer beyond the standard quantum limit by a factor of e(-r), where r is the squeezing parameter. In this study, we demonstrate that using squeezed light in combination with a quantum back-action nullifying meter in an optomechanical cavity with a mechanical mirror in the middle configuration can enhance the sensitivity beyond the standard quantum limit by a factor of e(-reff), where r(eff) = r + ln(4 Delta/zeta)/2, for 0

Summary: This paper studies the spontaneous emission dynamics of a two-level giant atom with dynamically modulated transition frequency and finds that the frequency modulation and retardation effect have a significant impact on the retarded feedback of the giant atom system, suppressing it. Furthermore, by introducing an additional phase difference, it is possible to achieve chiral and tunable temporal profiles of the output fields.

Summary: We propose a streamlined method for fast enantiomer-specific state transfer (ESST) of chiral molecules in cyclic three-level systems. By employing unitary SU(2) transformation and inversely engineering time-dependent Hamiltonians with designed Rabi frequencies, the left- and right-handed chiral molecules can evolve respectively to different excited states from their initial ground states simultaneously. Thus, a fast ESST is achieved.
