Summary: Based on the partial coherence theory, this study deduces the principle of spatial light interference microscopy (SLIM) and improves its calculation method. A double four-step phase shift method is proposed and experimentally demonstrated to address the problem of default phase assumption. Simulation results show that this method significantly reduces the relative error in reconstruction.

Summary: Measuring the polarization, spectrum, temporal dynamics, and spatial complex amplitude of optical beams is crucial for studying laser dynamics, telecommunications, and nonlinear optics. Current characterization techniques have limitations in certain contexts. This article introduces a method called spatial state tomography that overcomes these limitations and provides a complete description of an unknown beam by measuring spectrally, temporally, and polarization resolved spatial state density matrices. The method is demonstrated by characterizing the output of a vertical-cavity surface-emitting laser.

Summary: The interference effect in polarization space in heavy-ion collisions can be observed through the asymmetries of the decay angular distribution for vector meson photoproduction. A periodic oscillation pattern with transverse momentum is found to reasonably explain the second-order modulation in azimuth for the rho(0) decay observed by the STAR Collaboration.

Summary: This paper discusses the interference pattern produced by a quantum particle in Young's double-slit experiment, attributing it to the particle's wave function going through both slits. It shows how these path superpositions can be observed through minimally perturbing weak measurements and proposes a simplified protocol for observing these "weak trajectories" with single photons.

Summary: This Letter investigates Young's double-slit experiment with vector vortex beams, analyzing the results for various Poincare-Hopf index beams and studying the morphological changes in the far-field interference pattern. The Fraunhofer pattern consists of lattices of polarization singularities, the number of which varies based on the Poincare-Hopf index of the diffracted beam, with the number of intensity nulls along the vertical line equal to the absolute value of eta.

Summary: We propose a method of measuring the spatial coherence of light using a temporally modulated nonredundant slit array implemented on a digital micromirror device. Experimental results demonstrate that the spatial coherence for different slit separations can be accurately determined with a single measurement, even in the presence of background light.

Summary: The measurement and quantum arrival time problems in quantum theory have led to various predictions for the joint spatiotemporal distribution of particle detection events. This paper presents a feasible setup utilizing a modified double-slit experiment to test these predictions. Despite the successes of quantum mechanics, fundamental issues like the measurement problem and quantum arrival time problem have made the theory's predictions unclear and non-unique. The proposed unconventional double-slit configuration, achievable with present-day single-atom interferometry, allows for experimental distinction of these different predictions, contributing to a deeper understanding of the foundations of quantum mechanics.

Summary: The Young's double-slit interference of partially coherent polarization singular vector beams is investigated both theoretically and experimentally. The far-field interference pattern of these beams has spatial dependence in both horizontal and vertical directions, and its visibility is determined by the input spatial correlation length. The statistical properties of the diffracted beams, including intensity pattern, degree of polarization (DOP) distribution, and Stokes-parameters distributions, are strongly influenced by the spatial correlation length of the incident beam. The experimental results are in good agreement with the theoretical predictions, indicating potential applications in the field of light field statistics.

Summary: Wave-particle duality is a counterintuitive nature of quantum physics, and Young's double-slit interference is used as an example. In this study, frequency entanglement is used to create a nonlocal temporal double-slit interferometer, where the which-time information determines the behavior of the photons. By delaying one of the entangled photons, the mark of temporal distinguishability is prepared and its quantum eraser is implemented using spectrally resolved detection. These findings provide insights into the role of the temporal degree in quantum-light complementarity and photon interference.

Summary: This study aimed to correct stray light contamination caused by residual high-order aberrations using a statistical method, and apply it to ground-based slit spectra. The deconvolution process increased the RMS granulation contrasts to approximately 12.5%, with spectral lines becoming deeper in granules and shallower in inter-granular lanes. Additionally, the deconvolution process led to higher redshifts and blueshifts of spectral lines, indicating higher velocities of granulation in the solar photosphere.

Summary: In this study, the double-slit interference in single-photon ionization of the diatomic molecular ion H-2(+) is theoretically explored beyond the dipole approximation. Two effects, the single-atom nondipole effect and the two-center-interference one, were identified in the interference patterns of the photoelectrons from H-2(+), with the former having minimal impact on interference minima. This analysis suggests that interference minima may provide crucial information for decoding zeptosecond time delay in pulse-molecule interactions.

Summary: A simple chemical route to prepare water-soluble epitaxial Sr3Al2O6 thin films as sacrificial layers for future free-standing epitaxial complex oxide manipulation is proposed in this study. These thin films, prepared using metal nitrate and metalorganic precursors, exhibit dense, homogeneous, and epitaxial characteristics that can be easily etched for the fabrication of artificial heterostructures. This robust and cost-effective methodology has the potential to be applied in a wide range of thin film fabrication for advanced electronic, spintronic, and energy conversion devices beyond traditional applications.

Summary: The narrow spectral features of surface lattice resonances are highly suitable for the rational design of optical nanocavities aiming at enhanced light-matter interaction, ultrasensitive detection, or efficient light-energy conversion. Traditional fabrication methods for metal arrays are limited in scalability and adaptability, while template-assisted self-assembly offers a high-throughput approach for implementing colloidal plasmonic metasurfaces on various materials. In this study, pre-synthesized silver nanoparticles are used to construct versatile lasing architectures directly on the gain media, resulting in optical nanocavities with high-quality factors. The proposed architecture eliminates the need for an index-matching superstrate and allows for post-assembly modification of the plasmonic surface. Additionally, the angular dispersion of the metasurfaces is utilized to modify the angle of the lasing emission, achieving normal and off-normal lasing by adjusting the lattice parameter of the array. This research highlights the scalable and versatile nature of colloidal self-assembly techniques for the fabrication of plasmonic and photonic devices targeting advanced and non-linear optical phenomena.
