Summary: Nonlinear mechanics of solids is an exciting field that involves beautiful mathematics, instabilities, complex patterns, and various applications. By studying the formation of wrinkles in two-dimensional crystals and van der Waals heterostructures, researchers can gain finer control over parameters and offer atomistic interpretations of experimental observations. The relationship between the bending rigidity of the top membrane and the strength of the vdW interaction is shown to influence the number of radial wrinkles, demonstrating a nontrivial dependence on the number of layers and the alignment between the substrate and the membrane.

Summary: In this study, we demonstrate the electrical control of DMI and magnetic skyrmions in a Fe3GeTe2 monolayer through the ferroelectric polarization of an adjacent 2D vdW ferroelectric In2Se3. The results show that the magnitude and sign of DMI can be controlled by ferroelectric polarization reversal, leading to the creation and annihilation of skyrmions.

Summary: This study demonstrates that the anisotropic energy of a 2D antiferromagnet can be greatly enhanced by stacking it on a magnetic substrate layer. This enhancement is due to the sublattice-dependent interlayer magnetic interaction, which defines an effective anisotropic energy. It provides unique ways to control the antiferromagnetic order through the interlayer stacking order and the magnetic order of the substrate layer.

Summary: Nonwoven fibrous filter membranes are widely used in filtration due to their low cost. However, they are not effective in intercepting particles as small as the SARS-CoV-2 (COVID-19) virus. This study proposes a novel approach to enhance the performance of filtration membranes by reducing fiber size and coating fibers with metal. Experimental results show that this method improves filtration efficiency by incorporating van der Waals forces and electric Coulomb forces. The membrane combining both forces is almost four times more effective than a comparable membrane without the electric force.

Summary: In this study, the quasiparticle band structures and excitonic optical properties of SiC/MoSSe heterostructures were investigated using the GW + Bethe-Salpeter equation approach. The results show that all four stable structures of SiC/MoSSe heterostructures are favorable for producing high binding energy interlayer excitons. The modulation of optical dipole oscillator strength and radiative lifetimes is significant due to the different intrinsic dipole moments of MoSSe.

Summary: This paper explains how to dramatically increase the external near-field effect by replacing a plane wave or a Gaussian beam with a fully symmetric diffraction-free beam. This leads to deeply subwavelength focusing of the incident beam near the rear edge of the microcylinder, accompanied by a significant enhancement of the local electric intensity.

Summary: A hypothesis is proposed for the existence of perfect nonradiating modes in dielectric nanoparticles of an arbitrary shape. It is mathematically proven that such modes exist in axisymmetric dielectric nanoparticles and have unlimited radiation quality factors. By smartly tuning the excitation beams, perfect modes can appear as deep minima in the scattered radiation spectra (even complete disappearance), while experiencing substantial amplification of the fields inside the particle.

Summary: With the help of the original mathematical method for solving Maxwell's equations, it is shown that there are perfect invisibility modes or perfect non-scattering modes in dielectric waveguides. These modes allow light to propagate in free space at specific eigenfrequencies, making the optical fiber invisible and minimizing scattering losses. The properties of these modes in waveguides of circular and elliptical cross-sections are analyzed in detail.

Summary: In this paper, it is theoretically shown that a pair of plane waves impinging on a glass microcylinder under certain conditions may have a higher impact of evanescent waves, resulting in the suppression of the electromagnetic field in a specific area. This area, located in free space along the axis of the microcylinder, may serve as a linear optical trap for cold atoms and ions.
