Query: RKKY interaction of magnetic impurities in multi-Weyl semimetals   We have systematically investigated the Ruderman-Kittel-Kasuya-Yosida (RKKY)
interaction between two magnetic impurities in Weyl semimetals with arbitrary
monopole charge $Q$. We find that the RKKY interaction becomes intrinsically
anisotropic for $Q\geq2$, and its dependence on Fermi energy and impurity
separation is directly controlled by the monopole charge. With the increase of
$Q$, the RKKY interaction becomes more long-ranged and more anisotropic, which
makes interesting magnetic orders easier to form and thus may have important
applications in spintronics.
