Summary: Inspired by the microstructure of triclinic crystal material, lattice structures with twin boundaries were designed for energy absorption application. Introducing twin boundaries controls deformation mode and improves energy absorption performance, with both TCs and TBCCs showing increased energy absorption with more twin boundaries. The designed structures also follow the Hall-Petch relationship, confirming the feasibility of designing novel lattice structures by mimicking material microstructures.

Summary: Nonlinear lattices can support delocalized nonlinear vibrational modes (DNVMs) that are exact solutions to the dynamical equations of motion regardless of the lattice point interaction type and amplitude. By considering the space symmetry group of the fcc lattice, all one-component DNVMs can be derived and used to assess the accuracy of interatomic potentials through ab initio and molecular dynamics simulations. The presented family of exact solutions can estimate the accuracy of interatomic potentials for fcc metals at large displacements of atoms.

Summary: Traditionally, light transmission in optical devices relies on total internal reflection or photonic bandgaps, while the Dirac mode provides field confinement by utilizing the zero-density of radiation states around the Dirac point and features a unique algebraic decay profile. The Dirac mode in the Kagome lattice of photonic crystals exhibits an extremely high quality factor and can be used to control the all-range Dirac frequency by adjusting structural parameters, expanding its applications in modern integrated optical devices.

Summary: This study presents a design strategy for skyrmion host candidates based on magnetic spin and stereoactive lone-pair electrons. By synthesizing Fe(IO3)(3) and observing a predicted skyrmion phase, the researchers demonstrate a link between stereoactive lone-pair electron effects and enhanced Dzyaloshinskii-Moriya interaction, providing a new approach for chemical guidelines in the search for skyrmionic states of matter.

Summary: We provide a guideline for generating entanglement in quantum many-body states by applying the key ideas of the Higgs mechanism to systems without gauge structures. By demoting Z2 and U (1) gauge structures, we construct models with global Z2 X Z2 and global U (1) X Z symmetries respectively, which exhibit symmetry-protected-topological and gapless states. We also discuss the generalization of the model to different symmetries and lattices, as well as their potential applications to quantum simulators.

Summary: This study employs the Guided-Mode Expansion method to calculate the photonic band structure and quality factor of a photonic slab made up of a hexagonal lattice of air holes in a semiconductor material. It is observed that the dielectric constant of the semiconductor changes with pressure at a constant temperature, leading to an increase in frequency of a confined waveguide as pressure rises, while the quality factor decreases.

Summary: Evolutionary decisions to gift vertebrates with articulating structures, while refraining from doing so for invertebrates, are explored in this study. A material manipulation technique known as engineering on variable occupation of water (EVO) is introduced to create a dual mechanical mode material with extreme stiffness variations, allowing for on-demand switching between soft and hard states. This innovative approach opens up possibilities for the development and application of smart functional materials.

Summary: This paper explores the synthesis field of microporous zeolite-type materials and discusses the types of organic structure-directing agents (OSDA) that can be utilized for their crystallization. The study demonstrates the novelty of using hexamethylenetetramine (urotropine) as a structure-directing agent for open-framework silica polymorphs. By protonating urotropine in an acidic fluorine-containing medium, it becomes an efficient OSDA that leads to the formation of dodecasil 3C (MTN-type). The author also investigates OSDA-framework interactions in the MTN-type structure and proposes a unit cell model based on experimental data and Monte Carlo simulation.

Summary: Researchers have used femtosecond powder X-ray diffraction to study the transition from semiconductor to metal in Ti3O5 nanocrystals, finding that strain waves and electronic precursor phenomena determine the transformation pathway. The study demonstrates that in nanocrystals, picosecond switching occurs simultaneously with the propagating acoustic wavefront.

Summary: Optical-domain transient grating spectroscopy is a versatile background-free four-wave-mixing technique used to probe the vibrational, magnetic, and electronic degrees of freedom in materials. The recent development of coherent X-ray free-electron laser sources has extended this technique to the X-ray regime, offering advantages such as large penetration depth, element specificity, and short wavelengths for excitation grating with unprecedented resolution.

Summary: Modern techniques for investigating correlated materials in the time domain involve selective excitation in the THz frequency range and selective probing using x-ray scattering techniques. Cryogenic temperatures are often required to prevent thermal occupation of low energy modes. A specially optimized chamber has been developed for high-field THz excitation and x-ray diffraction experiments at sample temperatures between 5 and 500 K, successfully tracking the dynamics of structural, magnetic, and orbital order in different materials.

Summary: Using ultrafast resonant inelastic X-ray scattering, we have shown that femtosecond laser pulses can excite transient magnons at large wavevectors in gapped antiferromagnets, persisting for several picoseconds. Our work suggests that materials with isotropic magnetic interactions are preferred for achieving rapid manipulation of magnetism.

Summary: The study investigated the structural changes of water upon deep supercooling using wide-angle x-ray scattering at SwissFEL. It found that the oxygen-oxygen structure factor exhibited a strong increase in amplitude for the second diffraction peak, while q(2) showed an unprecedented positive partial derivative with respect to temperature below 236 K, indicating a less dense local ordering. The findings suggest that liquid water forms a pentamer-based hydrogen-bonded network with low density under deep supercooling conditions.

Summary: In this study, it is shown that certain lattice vibrations in cuprate high-T-c superconductors can induce transient terahertz reflectivity features suggestive of nonequilibrium superconductivity above the critical temperature. Time-resolved measurements reveal a three-order-of-magnitude amplification of a 2.5-THz electronic mode in driven YBa2Cu3O6+x. Theoretical analysis explains these observations by proposing an amplification mechanism for finite-momentum Josephson plasma polaritons. The study also emphasizes the significance of nonlinear mode mixing in amplifying fluctuating modes above the transition temperature in a wide range of materials.

Summary: Magnetic domain patterns in Tm-doped yttrium iron garnet (Tm:YIG) thin film can be locally imprinted by high intensity photon pulses of a hard x-ray transient grating (XTG). Micromagnetic simulations provide an understanding of the observed changes in magnetic domains orientation in Tm:YIG and XTG-induced changes. These results offer a route for the local manipulation of the magnetic state using hard XTG.
