Summary: The study investigates the time evolution of a Gaussian wave packet in a one-dimensional semiconductor with multiple potential barriers in order to determine the spin-based transmission, reflection, and trapping coefficients. The split-step finite difference method is utilized to solve the resulting nonlinear coupled Schrodinger equations. The scattering properties of the system are analyzed in relation to the Rashba and Dresselhaus spin-orbit interactions, wave-packet velocity, barrier geometry, and number of neighboring barriers. The results demonstrate that by adjusting the Rashba and Dresselhaus coupling strengths and system characteristics, control over the spin polarization and propagation coefficients of the wave packet can be achieved.

Summary: This paper investigates the spin-orbit torque and transport property in a 2D Rashba ferromagnetic electron gas. The longitudinal conductivity has two parts: one is determined by the charge density and independent of spin degrees of freedom, while the other is directly proportional to spin-orbit torque regardless of the band structure and temperature. This study reveals a general relationship between the transport property and spin-orbit torque. Additionally, the impacts of the spin-orbit coupling constant and Fermi energy on transverse conductivity and spin-orbit torque are discussed, providing helpful information for relevant experiments.

Summary: Researchers demonstrate a persistent spin helix in an organic-inorganic hybrid ferroelectric halide perovskite. They show that the spin-polarized band structure can be switched via an intrinsic ferroelectric field. This discovery has the potential to resolve the control-relaxation dilemma in spintronic devices.

Summary: The proximity effect in SNSOF and SF'F structures with spin-orbit interaction in the normal layer was theoretically investigated. It was found that the triplet correlations generated in the ferromagnetic layer can be effectively suppressed by a normal layer with spin-orbit interaction. The critical temperature of the superconducting layer in the SNSOF multilayer was higher compared to a similar multilayer without spin-orbit interaction in the normal layer. Additionally, a SNSOF structure with a mixed type of spin-orbit interaction was identified as a spin valve, with its critical temperature determined by the direction of the magnetization vector in the ferromagnetic layer. The control characteristics of the SNSOF spin valve were calculated and compared with traditional SF'F devices with two ferromagnetic layers. It was concluded that SNSOF structures with one controlled ferromagnetic layer have advantages over widely considered SF'F spin valves, making them promising for high-performance storage components in superconducting electronics.

Summary: Encapsulating robust Fe-based SCO molecules within the 1D cavities of single-walled carbon nanotubes (SWCNT) can endure encapsulation and positioning of individual heterostructures in nanoscale transistors, triggering a large conductance bistability and providing a backbone for readout and positioning of SCO molecules into nanodevices, as well as helping to tune their magnetic properties at the nanoscale. Spin-crossover molecules are ideal sensors due to their ability to change spin-state under various stimuli, but typically face limitations such as insulating and unstable properties, which can be overcome through encapsulation inside carbon nanotubes.

Summary: This study demonstrates that a strong 'spin'-orbit coupled one-dimensional hole gas can be achieved by applying a strong magnetic field to a cylindrical Ge nanowire. The induced subband dispersion of the hole gas has a similar form to that of the electron gas in the conduction band. The effective hole mass and 'spin'-orbit coupling have a small magnetic field dependence, while the effective g-factor of the hole 'spin' only has a small magnetic field dependence in the large field region.

Summary: Studies on the mechanical properties and texture evolution of aluminum 6201 alloys have shown that hardness is inversely proportional to electrical conductivity, with recrystallized grains coarsened by reducing dislocation density leading to a decrease in electrical conductivity. Highly strained alloys have more randomly oriented grains, affecting texture evolution.

Summary: The study of spin-orbit coupling (SOC) of light is crucial to explore the light-matter interactions in sub-wavelength structures. By designing a plasmonic lattice with chiral configuration that provides parallel angular momentum and spin components, one can trigger the strength of the SOC phenomena in photonic or plasmonic crystals. Our study gives insight into the design of novel plasmonic devices with polarization-dependent directionality of the Bloch plasmons. We expect spin-orbit interactions in plasmonics will find much more scientific interests and potential applications with the continuous development of nanofabrication methodologies and uncovering new aspects of spin-orbit interactions.
