Spin quadrupoletronics: moving spin anisotropy around [PDF]
, 2010 We show that spin anisotropy can be transferred to an isotropic system by transport of spin quadrupole moment. We derive the quadrupole moment current and continuity equation and study a high-spin valve structure consisting of two ferromagnets coupled to

Impurity ion transport by filamentary plasma structures
Nuclear Materials and Energy, 2019 We have studied the impurity ion transport by a filamentary plasma structure with the three-dimensional electrostatic particle-in-cell simulation. The effective diffusivity of the impurity ions transported by a filamentary plasma structure has been ...

Refining light impurity content estimates at the lower divertor based on experimental data in WEST
Nuclear Materials and Energy, 2023 WEST is an actively cooled, long-pulse tokamak with nearly all plasma-facing components (PFC) made of tungsten (W). One of the aims of WEST is to study plasma operation with W PFCs in preparation for long-pulse operation on W divertor devices like ITER ...

Impurity and Trace Tritium Transport in Tokamak Edge Turbulence [PDF]
, 2004 The turbulent transport of impurity or minority species, as for example Tritium, is investigated in drift-Alfv\'en edge turbulence. The full effects of perpendicular and parallel convection are kept for the impurity species. The impurity density develops

Stability of divertor detachment
Nuclear Materials and Energy, 2017 The 2D simulations of edge plasma transport show that unlike some earlier publications, the impurity radiation loss per se does not cause the bifurcation-like transition to detached divertor regime.

Effect of magnetic anisotropy on spin-dependent thermoelectric effects in nanoscopic systems [PDF]
, 2015 Conventional and spin-related thermoelectric effects in electronic transport through a nanoscopic system exhibiting magnetic anisotropy $-$with both uniaxial and transverse components$-$ are studied theoretically in the linear response regime.

Preliminary Result of Neoclassical Impurity Transport Affected by ICRH with a 4-D Fokker-Planck Code [PDF]
EPJ Web of ConferencesTo understand the role of ion cyclotron resonance heating (ICRH) in mitigating tungsten accumulation, we evaluate the impact of ICRH-induced poloidal asymmetries on neoclassical impurity transport using a newly developed 4-D Fokker–Planck code (FP4D ...

Modeling of hazardous impurities transport
Metalurgija, 2022 The considers solutions to the ecology problems, which set is formulated from cause-effect relationships. According to the adopted model, the equation’s coefficients for the harmful impurities transfer are attributed to the causal features of the process.
