Summary: Twisted light, a helical spatial mode carrying orbital angular momentum, has great potential in optical and quantum information applications. However, current experiments are hindered by bulky, expensive, and slow-response optical elements. Nanophotonics offers a solution by providing compact and multifunctional devices for generating and detecting twisted light modes.

Summary: The article introduces a platform that allows for the spontaneous generation and active manipulation of an optical vortex-antivortex pair using an external field. By utilizing an aluminum/silicon dioxide/nickel/silicon dioxide multilayer structure, a gradient-thickness optical cavity is created, where the magneto-optic effects of the nickel layer affect the transition between different topological phases. The vortex-antivortex pairs in the reflected light by the device are generated through mathematical singularities in the generalized parameter space of the silicon dioxide layers and exhibit polarization-dependent and topology-dependent dynamics driven by external magnetic fields.

Summary: Chemical machine learning relies on unique and informative representations of molecules. We present the matrix of orthogonalized atomic orbital coefficients (MAOC) as a quantum-inspired molecular and atomic representation that contains both structural and electronic information. MAOC is suitable for representing a wide range of chemical systems and shows accuracy similar or superior to other representations for various chemical properties.

Summary: This study investigates the manipulation and control of spin density and spin angular momentum of a probe field through control fields. The variation of spin density and distribution of the probe field can be controlled and modified by controlling the angle between interfering waves and adjusting the Rabi frequency of the control field.

Summary: In this study, it is shown that a significant magnetoresistance effect related to orbital current and spin-orbit torque (SOT) can be observed in Ni81Fe19/CuOx/TaN heterostructures with various CuOx oxidization concentrations. The migration of oxygen ions induced by ionic liquid gating modulates the oxygen concentration at the Ni81Fe19/CuOx interface, allowing for reversible manipulation of the magnetoresistance effect and SOT. The presence of a thick TaN capping layer enables internal oxygen ion reconstruction in the CuOx layer, which advances the development of spin-orbitronic devices through ionic engineering.

Summary: Harnessing structured light has multidisciplinary applications, including remote driving microrobots, sensing, communications, and ultrahigh resolution imaging. We experimentally demonstrated the generation of a vortex N-2(+) lasing using a wavefront structured near-IR femtosecond pulse. The efficiency of N-2(+) lasing generation is higher for the vortex pump beam compared to a plane wavefront pump beam at high pumping energy. Our results show the potential for remote structured N-2(+) lasing.

Summary: This study extends recent theoretical work by evaluating three-color reflection in a one-dimensional optical lattice filled with cold Rb-87 atoms using defects characterized by vacant lattice cells. The wider reflection band is sensitive to the number of random vacant cells, while the narrower bands are robust. All three reflection bands are robust against the number of continuous vacant cells. However, the narrower bands may widen and exhibit a blue shift when continuous vacant cells appear in the front of the lattice.

Summary: The atomic-scale structure and properties of material surfaces play a significant role in various chemical and mechanical phenomena. However, current methods for characterizing surfaces at the atomic level are limited by the need for strict environmental conditions. This study presents a new approach utilizing conductive atomic force microscopy (C-AFM) to achieve atomic-resolution surface imaging under ambient conditions. The results demonstrate the capability of this method to manipulate and observe surface structure and electronics in real time, with wide-ranging applicability.

Summary: In this study, a facile method for synthesizing CeO2/Ce-Co-LDH heterostructures has been demonstrated. The incorporation of Ce in Co-LDH leads to orbital overlap and adjustment of the electronic structure, while the oxygen-deficient CeO2 controls the charge transfer at the interface. This results in excellent water oxidation activity.

Summary: Transition-metal carbides have been widely studied as high-performance catalysts, but the catalytic properties of copper carbides have not been explored. By introducing subsurface carbon to Cu(111), a displacement reaction of a proton with a single Cu atom at atomic scale and room temperature is demonstrated. This novel Cu△+ surface, based on subsurface carbon doping, offers a new catalytic platform for on-surface synthesis.

Summary: A computational strategy was developed to explore the cyclical vertical manipulation of single atoms on the GaAs(110) surface, identifying tips capable of picking up and depositing an adatom. Success in manipulation depends on specific lateral and vertical tip distances, with a practical experimental protocol proposed for potential cyclical manipulation of single atoms on a nonmetallic surface.

Summary: In this study, submolecular resolution scanning tunnelling microscopy and qPlus atomic force microscopy were used to investigate the assembly of bi-isonicotinic acid on Au(111) and Ag(100) surfaces. The results showed that the formation of extended molecular rows is primarily driven by hydrogen bonding, and the influence of the substrate is relatively small. However, the surface does induce prochiral behavior and leads to the formation of a racemic mixture of rows with different handedness. A tiling model was adapted to the bi-isonicotinic acid system, providing insights into the growth kinetics and agreement with experimental observations of molecular morphologies.
