Summary: We observe cluster glasslike behavior in a double perovskite ruthenate Ba2CoRuO6 through various measurements. The system shows classic glassy characteristics such as frequency dependence in ac susceptibility, aging and memory effects, and short-range correlations that persist up to room temperature. The presence of significant antisite disorder and geometrical frustration allows for random distribution of various exchange interactions across the lattice, leading to the formation of locally dominant interactions and the development of short-range ordered clusters.

Summary: In this study, the charge transport characteristics of ISO molecules at the single-molecule level were investigated experimentally and theoretically. It was found that ISO molecules exhibit bias voltage-driven switching characteristics in single-molecule junctions. The mechanism behind the switch was identified as the shift of the frontier orbital energy levels of ISO molecules and the change of the interfacial electronic coupling with bias voltage. These findings will contribute to the design of high-performance bias voltage-driven molecular switches.

Summary: With the growing need for broadband wireless communication, high-resolution radar, security inspection, and biological analysis, terahertz (THz) technology has made significant progress in recent years. This progress has been possible due to the development of various THz functional devices, with metasurface being widely applied in these devices. However, constructing flexible THz metasurface devices remains a challenge due to the lack of flexibility in traditional semiconductor and metal materials. In this study, a two-dimensional material called MXene was used to create flexible metasurfaces with frequency filtering and polarization functions. These metasurfaces, combined with vanadium dioxide, showed excellent amplitude modulation performance under electrical stimulation. The flexibility and high integration of this active metasurface make it useful in THz imaging and sensing systems.

Summary: Recently, the magnetic response of synthesized graphene triangulene chains was analyzed using scanning tunneling microscopy methods. Building on this study, the exchange bilinear and biquadratic constants of the chains were determined through calculations of two-spin rotations. The analysis focused on open-ended, odd-numbered chains that exhibited a triplet ground state formed by paired edge states. Three experimental approaches to trigger and control a singlet-triplet spin transition were proposed, including two methods based on mechanical distortion and one method based on the application of an electric field.

Summary: This paper investigates the nonlinear dynamic behavior of aniso-visco-hyperelastic DEMES actuators and explores the effects of anisotropy on their performance. The study reveals that material anisotropy enhances the equilibrium angle and resonant frequency of the structures, leading to a favorable impact on their actuation performance. The analytical model and trends presented in this study can be potentially utilized in the design and development of anisotropic DEMES actuators under time-dependent actuation.

Summary: In this study, a high-resolution structural analysis of Et2Me2Sb[Pd(dmit)2]2 salt reveals the existence of an intermediate incommensurate phase between the highly frustrated room temperature phase and the charge separated phase. This phase shows no modulation of the Pd-Pd distance but a large steric effect between the cation and the terminal sulfur atom of the Pd(dmit)2 molecules.

Summary: In this study, the spin current in a FeRh/Cu heterostructure during the ultrafast magnetization process is directly measured, revealing a significant correlation between the spin current and the magnetization dynamics. This suggests an angular momentum transfer mechanism from electrons to magnons, involving spatial transport and dissipation of angular momentum. This finding contributes to a better understanding of laser-induced ultrafast magnetization processes.

Summary: In this study, three host defense peptides (HDPs) exhibited potent and broad-spectrum antimicrobial activity against aquatic pathogenic bacteria and effectively modulated anti-infective immune responses in largemouth bass. They also showed potential in combating biofilm-related infections and significantly enhancing the survival rate of bacteria-challenged largemouth bass while decreasing bacterial resistance compared to conventional antibiotics. These results suggest the promising use of these HDPs as novel anti-infective agents in largemouth bass culture.

Summary: Metallic topological boundary states at the boundary between topological non-trivial and trivial phases are usually gapless. We observed incommensurate charge density wave (CDW) formed on the topological boundary states of CoSi (001) surface driven by electron-electron interactions. The wavevector of CDW varies with temperature, coinciding with the evolution of topological surface Fermi arcs. The orientation of the CDW phase is determined by the chirality of the Fermi arcs, indicating a direct association between CDW and Fermi arcs. Our finding will stimulate the search for more interaction-driven ordered states, such as superconductivity and magnetism, on the boundaries of topological materials.

Summary: Photon-induced near-field electron microscopy (PINEM) allows for near-field imaging with nanometer spatial resolution and femtosecond temporal resolution. We studied an asymmetric copper bowtie nanostructure and analyzed its plasmonic near-field distribution and lifetime. PINEM images revealed surface plasmon polaritons and local surface-plasmon resonance excitations with different polarizations. The distribution and intensity variations of the near-field were analyzed using finite-element simulations. This study provides important insights for the manipulation of plasmonic near-field and the design of plasmonic devices.

Summary: This study investigates the temperature dependences of resistivity, Hall effect and magnetoresistance of FeTe thin films with different amounts of excess Fe and oxygen. The results show that the oxygen-annealed samples exhibit positive Hall coefficients, while the vacuum-annealed samples transition from positive to negative below 50 K. Both the resistivity and Hall coefficient of all samples display a significant drop at around 50 K-75 K, indicating the coexistence of superconductivity and antiferromagnetic order in the oxygen-annealed samples. Additionally, the oxygen-annealed samples show dominant negative magnetoresistance, while the vacuum-annealed samples exhibit both positive and negative values. Oxygen annealing is found to reduce the excess Fe in FeTe, which has been previously overlooked. The findings are discussed in relation to the understanding of oxygen-annealed FeTe thin films in comparison with FeSe1-x Te (x).

Summary: This study theoretically analyzes the effects of photoinduced coherent transverse and longitudinal acoustic phonons on electron diffraction and provides a guide for the exploitation and modulation of coherent phonons. Simulation results show a complex relationship between the frequencies of the phonons and diffraction signals, depending on the laser penetration depth, sample thickness, and temporal stress distribution. Additionally, an intensity decomposition method is proposed to explain the in-phase oscillation and high harmonics caused by inhomogeneous excitation.

Summary: This study systematically investigates the evolution of fine electronic structures in superconducting LnO1-xFxBiS2 (Ln denotes lanthanoid) using spin- and angle-resolved photoemission spectroscopy. The results show that the shape of the Fermi surface changes from elliptical to rectangular at the X point with increasing electron doping, which is a common phenomenon in different lanthanide systems. Additionally, an emergent large Fermi surface around the tau CYRILLIC CAPITAL LETTER GHE point is observed in all samples with different doping levels, deviating from theoretical predictions and potentially related to superconductivity. Furthermore, a humped band around X(ir,0) is found in highly doped samples, possibly attributed to BiS2 surface reconstruction or surface defects depending on the electron concentration. The study also demonstrates the spin-selective excitation of photoelectrons, indicating the presence of spin-orbital-entangled bulk Rashba splitting in this system, which may enable the optical tuning of electron spin in a BiS2-based system.
