Summary: The study explores the potential existence of spin texture in the bilayer cuprate superconductor Bi2Sr2CaCu2O8+delta using cluster dynamical mean-field theory. The spin texture circulates in the same direction around k=(0,0) and k=(pi,pi) and remains stable against the superconducting phase. The amplitude of the spin structure is significantly affected by the pseudogap phenomenon, more so than the spectral function itself.

Summary: Spin angular momentum associated with circular polarization is a fundamental aspect of photons in both classical and quantum optics. Transverse spin, perpendicular to the mean wavevector, plays a significant role in confined electromagnetic waves and leads to interesting topological spin structures and properties in the optical near-field. The concepts of spin photonics have importance in various fields like optics, topological photonics, metrology, and quantum technologies.

Summary: The study found that spin-triplet pair correlations can be generated in a simple structure without the use of ferromagnetic elements. By observing the local electronic and magnetic properties, it was confirmed that the spin-orbit generated magnetization comes from equal-spin pairs rather than their orbital motion.

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: Quasisymmetry is an approximate symmetry that emerges in low-energy effective theory and commutes with the Hamiltonian at a lower order. It adds desirable properties to the system, such as large Berry curvatures due to small band gaps, which are robust against perturbations.

Summary: A significant enhancement of Rashba spin-orbit coupling (RSOC) achieved at a superconducting amorphous-Hf0.5Zr0.5O2/KTaO3(110) heterointerface under light illumination is reported. The RSOC strength can be as high as 1.9 T in the normal state and increases to a peak value of 12.6 T under light illumination near the Lifshitz transition point, showing great potential for spintronics.

Summary: This study investigates the effects of spin-independent hybridization potential and spin-orbit coupling on a two-band superconductor with equal-time s-wave interband pairing order parameter. By analytically solving the Gor'kov equations, the symmetry classes of Cooper pairs are studied based on two-band degrees of freedom. The results show distinct symmetry classes for different pairing correlations in the two-band superconductor, with spin singlet and spin-triplet cases demonstrating unique characteristics under the influence of spin-independent hybridization and spin-orbit coupling.

Summary: Spin-orbital coupling and parity-time symmetry are of great importance in various fields such as condensed matter physics, cold atom physics, optics, and acoustics, and have potential applications in spintronics, quantum computation, sensors, and other functionalities. In this study, it is shown that a new type of SOC, called imaginary SOC, can be synthesized in a PT-symmetric pseudo spin-1/2 system. This SOC can substantially change the energy spectrum, generating a double-valleys structure and tunable complex energy bands. Potential experimental realizations are proposed in cold atomic gases and systems of coupled waveguides.

Summary: We construct families of one-dimensional stable solitons in two-component PT-symmetric systems with spin-orbit coupling and quintic nonlinearity. The stability regions for the solitons are identified, and the stability boundaries are determined by simulations and linear stability analysis. The evolution scenarios for unstable solitons are investigated, and interactions between adjacent solitons are explored. The study also considers a reduced diffractionless system that only produces unstable solitons.

Summary: A theoretical study is conducted to investigate the effect of an in-plane magnetic exchange field on the band structure of noble metals and topological insulators films. The results show that the exchange field induces spectrum distortions of the surface states and causes exotic redistribution of the spin density, suggesting that large-angle electron scattering within the film dominates at certain energies.

Summary: Spin-orbit interaction is important for enhancing the in-plane upper critical field of two-dimensional superconductors. A LaAlO3/KTaO3 (111) superconducting interface with a high in-plane upper critical field (approximately 1.6 T) was reported, which is about 1.8 times the Pauli paramagnetic limit. The H-T superconducting phase diagram was well-fitted by the Klemm-Luther-Beasley (KLB) theory, and the spin-orbit scattering (SOS) length was approximately 32 nm. Additionally, normal-state magnetotransport measurements showed weak antilocalization signatures caused by strong spin-orbit coupling in LaAlO3/KTaO3 (111). The spin diffusion length derived from magnetotransport measurements was 40 nm at 2 K, comparable to the SOS length.
