DOI: 10.1073/pnas.2215030120
Abstract: While the effective g-factor can be anisotropic due to the spin-orbit interaction (SOI), its existence in solids cannot be simply asserted from a band structure, which hinders progress on studies from such viewpoints. The effective… read more here.

DOI: 10.1103/physrevb.102.041203
Abstract: First-principles simulations are conducted to predict that ferroelectric nitride perovskite $\mathrm{LaW}{\mathrm{N}}_{3}$ not only exhibits large spin splittings (2.7 eV \AA{}) but also possesses unique spin textures for some of its conduction levels. Such spin splittings… read more here.

Abstract: We report the first observation of a large spin-lifetime anisotropy in bilayer graphene (BLG) fully encapsulated between hexagonal boron nitride. We characterize the out-of-plane (τ_{⊥}) and in-plane (τ_{∥}) spin lifetimes by oblique Hanle spin precession.… read more here.

Abstract: Building on the mapping of large-S spin chains onto the O(3) nonlinear σ model with coupling constant 2/S, and on general properties of that model (asymptotic freedom, implying that perturbation theory is valid at high… read more here.
