Summary: Enantiomorphic right- and left-handed polyproline type I helices have been observed for the first time in four cyclic dodecapeptoids with methoxyethyl and propargyl side chains using single crystal X-ray diffraction. The absence of NH hydrogen bonds in peptoids reveals the role of intramolecular backbone-to-backbone interactions and CH hydrogen bonds in stabilizing the macrocycle conformation. Additionally, intramolecular backbone-side chain C5 CH hydrogen bonds emerge as a stabilizing factor.

Summary: This article proposes a novel reconfigurable reflectarray (RRA) with 1 bit beam scanning and switchable linear, left-handed (LH) circular, or right-handed (RH) circular polarization. A 10 x 10 RRA was prototyped with each unit cell using only two p-i-n diodes to implement dual functions. The fabricated RRA can experimentally demonstrate 2-D beam scanning and polarization switching among 45 degrees/135 degrees linear polarization and LH/RH circular polarization.

Summary: Research shows that people's aesthetic preferences for image orientation are influenced by their left/right reading habits. Food images presented in a direction that is easier to grasp and bring to the mouth are preferred by participants. This suggests that the orientation of food images can impact preferences and that people tend to prefer images that are easy to interact with.

Summary: In this study, the dynamics of modulated waves in an alternate right-handed and left-handed multi-coupled nonlinear dissipative discrete electrical lattice are analytically investigated. The damped 2D complex Ginzburg-Landau equation governing wave propagation in this system is derived, and criteria for instability of modulated Stokes waves are established. The presence of a dispersive element is shown to soften the network system's instability.

Summary: The self-assembly of cellulose nanocrystals in a tilted cuvette leads to the formation of rainbow color films that can simultaneously reflect left-handed and right-handed circularly polarized light, with a maximum reflectance value of approximately 72%. This unique ambidextrous optical reflection arises from left-handed chiral photonic architectures with lateral gradient photonic bandgaps and nematic-like defects.

Summary: Dual-band composite right/left-handed transmission lines with nonreciprocal phase shift controlled by external magnetic field are proposed and demonstrated. The dynamic change in the nonreciprocal phase gradient enables the realization of dual-band and unidirectional leaky-wave antennas without frequency-dependent change in beam direction. A prototype nonreciprocal metamaterial line using polycrystalline yttrium iron garnet is fabricated and measured for verification.

By choosing appropriate transfer phases and strengths of the driving fields, both directional amplification and isolation with bi-directional nonreciprocity can be achieved.

Summary: This paper investigates the dynamical Anderson transition of a single particle in a 1D incommensurate potential under periodic driving and uncovers rich yet unexplored phenomena. The probability density distribution of the ratio of nearest quasi-eigenenergy spacings is obtained numerically, and two statistical measures are proposed to detect the dynamical transition. Additionally, the Anderson transition can also be identified using pseudo-spin operators based on the site bases.

Summary: We propose a method based on quantum correlation function to discriminate chiral molecules. The method utilizes a cyclic three-level model in a driven cavity-molecule system, where the inherent properties of electric-dipole transition moments of chiral molecules are employed for discrimination. Our results show that left- and right-handed chiral molecules can be distinguished by detecting the quantum correlation function. This is of great importance for chirality discrimination in pharmacology and biochemistry.

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: In this study, sympathetic cooling in an optomechanical system consisting of two coupled cantilevers is proposed. The scheme involves feedback cooling of a symmetric mode and indirect cooling of an anti-symmetric mode through parametric coupling. Coherent dynamics is found to be crucial for sympathetic cooling, with optimal cooling achieved when the mechanical dissipation rate and coupling strength are comparable. Increasing the mode coupling strength improves sympathetic cooling, and the cooling limit imposed by feedback cooling is reached when the effective temperatures of the two modes approach the strong coupling condition. The research opens up possibilities for extending cooling techniques to coupled mechanical resonators and their applications in sensing and information processing.

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.

Summary: In this paper, we study the decay dynamics of a two-level giant atom coupled to a waveguide with time-dependent coupling strengths. In the non-Markovian regime, we find that the dynamics of the atom depend on the atom-waveguide coupling strengths at an earlier time, allowing for tailored decay dynamics and the possibility of stationary population revival. Additionally, we demonstrate the potential to simulate quantum Zeno and anti-Zeno effects in the giant-atom model with periodic coupling quenches.

By controlling the time interval between the consecutive pulses of pump lasers, the emission of phonon pairs can be tuned. The experimental results show the system behaves as an antibunched phonon-pair emitter. The proposal can be extended to achieve an antibunched n-phonon emitter.
