Summary: This study reveals the mechanism of linear and nonlinear localization induced by spatially periodic modulation of spin-orbit coupling. It shows that specific chemical potential can lead to localized solitons or vortex solitons, and their stability strongly depends on the potential's location in the gaps.

Summary: We report a type of kink-like breathers in one-dimensional Bose-Einstein condensates with helicoidal spin-orbit coupling. The kink amplitude and shape of the breather can be adjusted by the strength and period of the spin-orbit coupling. Our findings demonstrate that the oscillating intensity of the breather can be controlled by adjusting the initial kink amplitude.

Summary: This paper demonstrates the existence of modulational instability in nonlinear exciton-polariton condensates. The growth rate expression is derived through linear stability analysis of continuous waves, and a parametric study of modulational instability is conducted. The results show that the photonic spin-orbit coupling and the pumping power have an impact on the growth rate spectrum.

Summary: The generation of a robust spin current with both in-plane and out-of-plane spin polarization is demonstrated in epitaxial thin films of the chiral antiferromagnet Mn3Sn in proximity to permalloy thin layers. The in-plane polarized spin current is generated from the interior of Mn3Sn and follows its temperature dependence, while the out-of-plane polarized spin current arises from the spin swapping effect at the Mn3Sn/permalloy interface.

Summary: Researchers studied the interaction among laser illumination, spin, and topology in a two-dimensional material with spin-orbit coupling using Floquet scattering theory and atomistic models, showing how laser illumination can disrupt topological edge states and generate pure spin photocurrents and spin-polarized charge photocurrents. This paves the way for the generation and control of spin-polarized photocurrents.

Summary: This paper investigates the behavior of electronic current in a one-dimensional lead with spin-orbit coupling. The study focuses on the injection of this current into a metallic conductor through two contacts, forming a closed loop. The results show that, under the influence of an external potential, the current becomes spin-dependent and interferes with itself to create spin-polarized interference patterns. This discovery has significant implications for spintronics applications.

Summary: Recent research on ultra-cold quantum gases has revealed that dipolar Bose-Einstein condensates with local and nonlocal interactions exhibit complex spatiotemporal dynamics. In this study, we investigate the possibility of controlling soliton molecule formation and dynamics in binary dipolar condensates with spin-orbit coupling. By employing the variational technique, we derive new equations of motion for the widths, amplitudes, potential, and oscillation frequency of the molecules. Our findings confirm the existence of stable localized bound states in an optical potential and indicate that the integrity of the molecules is influenced by physical parameters and the presence of spin-orbit coupling. The Vakhitov-Kolokolov criterion is used to select these parameters and ensure molecular stability. Numerical experiments support our analytical predictions, and we also observe soliton-soliton interactions within each molecule under strong local interactions.

Summary: This study analytically obtained the critical condition for phase transition of Bose-Einstein condensates with equal-weight Rashba and Dresselhaus spin-orbit coupling in a one-dimensional optical lattice, revealing rich competitive relationships. The change in energy minima and phase transition point by the optical lattice was found to depend on atomic interactions and spin-orbit coupling. The theoretical evidence provided a deep understanding of the competition mechanism between optical lattice and spin-orbit coupling for ground state phase transition.

Summary: In this study, we apply the imaginary time evolution method (AITEM) to investigate the system of Gross-Pitaevskii equations in a binary atomic Bose-Einstein condensate with spin-orbit coupling (SOC) and Rydberg-Rydberg interaction (RRI). We find stable solitons in the two-dimensional system and discuss their stability based on norm and energy. Additionally, we demonstrate that these solitons can be effectively controlled by the local and nonlocal nonlinearities of the system.

Summary: This study demonstrates the control of spin-triplet Cooper pairs in superconducting/ferromagnet heterostructures using magnetic proximity effect and spin-orbit coupling. The fabricated Co/Nb/Pt heterostructures successfully suppress the critical temperature (T (C)) and modulate the superconducting properties through independent control of spin-orbit coupling and magnetic proximity effect. These findings offer a new approach for the design of superconducting spintronics devices.

Summary: In this study, we analyze the relationship between Dresselhaus spin-orbit coupling, dipole-dipole interaction, and ground-state phases in an anharmonic trap. The results reveal that different structural phase transitions can be achieved by adjusting the magnitudes of D-SOC and DDI, leading to novel topological configurations.

Summary: The study elucidates a mechanism behind the enhancement of magnetic-dependent charge-to-spin conversion in ferromagnetic materials, highlighting the dominant role of interfacial contribution and the potential for control via interfacial band engineering. It shows that the efficiency of charge-to-spin conversion in ferromagnets surpasses other materials with reduced symmetry.

Summary: We find that long-range and attractive fermion-mediated interactions between bosons have dramatic effects on the properties of the bosons. The phase diagram consists of a stable region of mixing and unstable region toward phase separation. The induced interaction not only enhances the repulsion between the bosons against collapse but also enhances the stability of the superfluid state by suppressing quantum depletion.
