论文摘要
我们研究了三维DIRAC/WEYL SEMIMETAL中无耗散磁性磁性效应。大厅的电阻率$ρ_{yx} $和热电堂系数$α_{xy} $以量子限制显示高原，其中电子仅占据Zeroth Landau级别。在这种情况下，抑制了Seebeck系数$ S_ {XX} \大约ρ_{YX}α__{Xy} $中的量子振荡，并将无质量的费米子转化为费米液体系统。我们表明，量子极限处的seebeck系数由费米波长的谐波和通过磁长度缩放的谐波波长的谐波总和。
We investigate dissipationless magneto-Seebeck effect in three-dimensional Dirac/Weyl semimetal. The Hall resistivity $ρ_{yx}$ and thermoelectric Hall coefficient $α_{xy}$ exhibit plateaus at the quantum limit, where electrons occupy only the zeroth Landau level. In this condition, quantum oscillation in the Seebeck coefficient $S_{xx}\approx ρ_{yx}α_{xy} $ is suppressed, and the massless fermions are transformed into a Fermi liquid system. We show that the Seebeck coefficient at the quantum limit is expressed by the harmonic sum of Fermi wavelength and thermal de Broglie wavelength scaled by magnetic length.
