Large anomalous Nernst effect in a skyrmion crystal
Thermoelectric properties of a model skyrmion crystal were theoretically investigated, and it was found that its large anomalous Hall conductivity, corresponding to large Chern numbers induced by its peculiar spin structure leads to a large transverse thermoelectric voltage through the anomalous Nernst effect. This implies the possibility of finding good thermoelectric materials among skyrmion ...
متن کاملScattering-independent anomalous Nernst effect in ferromagnets
Using the full-potential linearized augmented plane-wave method within the density functional theory, we compute all contributions to the scattering-independent part of the thermoelectric conductivity tensor α̂, namely, the intrinsic contribution α̂ic and the side-jump contribution α̂sj. For the ferromagnetic materials bcc Fe, hcp Co, fcc Ni, and L10 ordered alloys FePd and FePt, our investigation...
متن کاملQuantum Nernst Effect in a Bismuth Single Crystal
We report a theoretical calculation explaining the quantum Nernst effect observed experimentally in a bismuth single crystal. Generalizing the edge-current picture in two dimensions, we show that the peaks of the Nernst coefficient survive in three dimensions due to a van Hove singularity. We also evaluate the phonon-drag effect on the Nernst coefficient numerically. Our result agrees with the ...

15 صفحه اولAnomalous bending effect in photonic crystal fibers.
An unexpected transmission loss up to 50% occurs to intense femtosecond pulses propagating along an endlessly single-mode photonic crystal fiber over a length of 1 m. A specific leaky-fiber mode gains amplification along the fiber at the expense of the fundamental fiber mode through stimulated four-wave mixing and Raman scattering, leading to this transmission loss. Bending near the fiber entra...
