Dirac金属中的磁输运:手征磁效应和量子振荡

Magnetotransport in Dirac metals: chiral magnetic effect and quantum oscillations

Gustavo M. Monteiro, Alexander G. Abanov, Dmitri E. Kharzeev

摘要:

狄拉克金属的特征是费米准粒子的线性色散,狄拉克点隐藏在费米面内。我们利用手征动力学理论研究了这类材料的磁输运性质,在同一框架内描述了手征磁效应引起的负磁阻效应和费米面的存在引起的磁阻效应的量子振荡。我们讨论的相关性所获得的结果,最近的测量${\rm Cd_3As_2}$。

英文摘要:

Dirac metals are characterized by the linear dispersion of fermionic quasi-particles, with the Dirac point hidden inside a Fermi surface. We study the magnetotransport in these materials using chiral kinetic theory to describe within the same framework both the negative magnetoresistance caused by chiral magnetic effect and quantum oscillations in the magnetoresistance due to the existence of the Fermi surface. We discuss the relevance of obtained results to recent measurements on ${\rm Cd_3As_2}$.
