Summary: The authors demonstrate that phase singularities can be created and controlled, all optically, in a simple thin film of organic molecules using cavity-free strong light-matter coupling. This finding not only opens up new possibilities for the application of strong light-matter coupling, but also provides a new, simplified, and more versatile means of manipulating phase singularities.

Summary: This article describes the new types of states of matter generated by strong correlations, including quantum criticality, superconductivity, and topological phases, and discusses their potential in quantum applications. Recent developments have shown that strong correlated systems are not always adiabatically connected to their non-interacting counterparts, and the quantum phases and fluctuations they create can defy traditional notions.

Summary: This study evaluated the longitudinal correlations between intravoxel incoherent motion (IVIM) and dynamic contrast-enhanced (DCE) parameters in prostate cancer patients receiving radiation treatment. The results showed an increase in both IVIM and DCE parameters during treatment, indicating a measurable response to radiation treatment with both techniques. Significant but low longitudinal correlations were found between some IVIM and DCE parameters in the peripheral zone and transition zone.

Summary: The question of whether strong correlations can lead to gapless topological states is addressed in this study. A general approach is proposed, where strong correlations cooperate with crystalline symmetry to produce gapless topological states. The approach is tested using Kondo lattice models and materials with different electronic degeneracies promoted by space-group symmetries. The study demonstrates the potential of this materials design principle in discovering new topological metals in strongly correlated systems.

Summary: The research focuses on the electronic topology in metallic kagome compounds, presenting transport experiments in Na2/3CoO2 which show evidence for the coexistence of light and heavy carriers. At low temperatures, the dominant light carrier conductivity is suppressed by B-linear MR, suggesting the presence of Dirac-like quasiparticles.

Summary: The correlations in speckle patterns generated by scattering of perfect optical vortex beams were studied to produce a new class of coherence functions called Bessel coherence functions. Higher (zeroth) order Bessel coherence functions were realized through cross (auto)-correlation between speckle patterns generated by scattering of perfect vortex beams of different orders. It was observed that the divergence of the produced Bessel coherence functions varied linearly with the order of the coherence function, with experimental results confirming analytical findings.

Summary: The study demonstrates the importance of the Pauli principle in strong field processes involving multiple active electrons, even in the nonrelativistic regime. By analyzing momentum correlations of three outgoing electrons, the different symmetries of electronic wavefunctions directly related to the initial state spin components become clearly visible.

Summary: Fresnel incoherent correlation holography (FINCH) is a well-established imaging technique, and a modified approach allowing for implementation through a single camera shot has been introduced recently. The study reveals the necessity of a reconstructing function completely independent of the function of the phase mask for faithful expression of the characteristics of the modulating function in image reconstruction.

Summary: This study focuses on the motion of a vortex dipole in a two-dimensional holographic superfluid, achieving high-precision matching with the dynamics from the Gross-Pitaevskii equation. By comparing with equations describing vortex interactions in superfluids, the friction parameters of the holographic superfluid are successfully determined, indicating the potential application of holographic vortex dynamics in experimentally accessible superfluids.

Summary: Colloidal gel systems exhibit slow relaxation and long-ranged spatial correlations of dynamics in the presence of long-ranged stress correlations, which have been largely unexplored. In this work, we investigate stress correlations in soft colloidal gel materials with moderate to high packing fractions and strong attraction. We find that the stress correlations are long-ranged and the gel materials do not behave as normal elastic solids near the gel point.

Summary: The study investigates the impact of nanoparticle size and density on critical current in (Y-0.77, Gd-0.23)Ba2Cu3O7-delta films. It demonstrates consistency between the field-dependent critical current and expectations from strong pinning theory. The dependence of vortex creep rate on nanoparticle size and density roughly mirrors that of alpha.

Summary: Light scattering by disordered media is a widespread phenomenon where the random phase acquired by the light can mask or destroy associated information. Efficient filtering of the random wavefront can be achieved by mixing noisy optical modes of various complexity in a second-order nonlinear medium without using correlation-based calculations.

Summary: The study found that Thimerosal (TM) binds to Cys residues in hemoglobin, causing conformational changes and harmful effects on oxygen uptake. Experimental results showed that the concentration, incubation time, and temperature of TM significantly affected oxygen uptake. TM also influenced sulfhydryl content, production of reactive oxygen species, and membrane fragility of erythrocytes.

Summary: Preparation, control, and measurement of optical vortices are crucial in fundamental science and optical technology applications. In this study, we demonstrate the modulation of light by light using nonlinear optical interactions to identify the topological charge of optical vortices. The spatial cross modulation between an optical vortex and a triangular shaped beam results in a triangular-lattice pattern in the light beams. Our results show that this cross modulation method can be used for a variety of spatial field structures.

Summary: We report on a non-Rayleigh, nondiffracting speckle field that is an exact solution to the scalar Helmholtz equation. We have demonstrated that these fields can be directly optimized to a continuous range of contrast values corresponding to sub-Rayleigh or super-Rayleigh statistics while maintaining their nondiffracting characteristics. Additionally, this work expands the range of non-Rayleigh statistics of nondiffracting fields, which could have numerous applications in solid-state physics, cold atoms, and optical imaging.

Summary: In this study, annular waveguides were fabricated inside a glassy blade using direct laser writing technique, demonstrating the generation of orbital angular momentum beams with different topological charges in the same structure. By choosing appropriate waveguide parameters and tilting the input wavefront, the topological charge of a beam can be adjusted. This work offers opportunities for optical communications using multiplexed beams with spatial degrees of freedom, as well as for generating tunable angular momentum at microscale for lab on chip integrability.
