Summary: In this study, the two-dimensional energy-momentum-tensor distributions of the nucleon on the light front were investigated using Abel transforms. It was found that the main features of all EMT distributions remained intact during the Abel transform process. Equivalence between global and local stability conditions for the nucleon in different frames was examined, along with discussions on the two-dimensional force fields within a nucleon on the light front.

Summary: This study provides new information about the spin structure of the pion by investigating the correlation between quark spin and orbital angular momentum. The results show that the correlation in the pion is antialigned. Additionally, the correlation in terms of x and transverse momentum kT is compared between the GPD approach and the GTMD approach.

Summary: The chiral property of a sphere can optimize the spin-orbit interaction, leading to an enhanced transverse shift. By adjusting the handedness of the chiral sphere and the helicity of the incident beam, a transfer of spin angular momentum to orbital angular momentum is achieved, resulting in the observed increase in transverse shift. These findings are of significance for the quantitative measurement of chiral nanoparticles and related applications.

Summary: Spin-orbit interactions (SOIs) involve the coupling of spin and spatial degrees of freedom of light, with spin-Hall effect of light (SHEL) being a unique example. Experimental study of SHEL due to forward scattering of linearly polarized Gaussian and Hermite-Gaussian beams from a silver nanowire reveals spin-dependent antisymmetric intensity patterns. The results show significant enhancement of the spin-Hall signal for the Hermite-Gaussian beam compared to the Gaussian beam, with longitudinally spinning fields being the primary reason for the effects.

Summary: This study presents simulation and experimental results on measuring the spin Hall effect of light (SHEL) at approximately 0.12 degrees away from normal incidence. The measurement is achieved by detecting the transverse spin-shift caused by polarization variations in the reflected beam. This research opens up possibilities for applications in material characterization using retro-reflection geometry.

Summary: We investigate the mechanical structure of a spin-1 particle and analyze the energy-momentum tensor distributions in different frameworks. In the 2D Breit frame, the mass and pressure distributions have additional monopole contributions induced geometrically. The 2D infinite-momentum frame exhibits induced dipole contributions to the mass, pressure, and shear-force densities, which can be visualized when the spin-1 particle is polarized along the x-axis.

Summary: Recent studies have shown the existence of optical forces and torques in sub-wavelength evanescent fields. Analytically, it was demonstrated that guided modes with transverse spin density induce optical torques. Hybrid modes supported by cylindrical waveguides exhibit intrinsic helicity leading to a rich distribution of longitudinal optical torques.

Summary: This article explores how a dimer made up of two nanoparticles can obtain energy from a random electromagnetic field and achieve direct motion through asymmetries in the particles. The study finds that the force is non-zero only when at least one of the particles is absorbent. Additionally, it demonstrates that the nonreciprocity of the force leads to nonconservative interaction dynamics.

Summary: In this article, we use an exact method to study the fields scattered by a spherical magneto-optical particle and calculate the optical forces exerted on it. The resulting force and its components, namely the magneto-optical gradient force and magneto-optical extinction force, are presented analytically. We also derive analytical expressions for the scattering and extinction cross sections of the particle, which intuitively demonstrate the effect of circular dichroism in magneto-optical scattering and forces. Furthermore, we show that the magneto-optical extinction force is a result of circular dichroism in magneto-optical scattering, and the directional scattering is related to the force exerted on the particle.

Summary: By preparing colloidal crystals with random missing scatterers, crystals are created where disorder is embodied as vacancies in an otherwise perfect lattice. In this system, there is a critical defect concentration where light propagation undergoes a transition from a perfect reflector to an enhanced transmission phenomenon. This behavior can be phenomenologically described in terms of Fano-like resonances.
