通过进行重正化群分析，研究了由长程库仑相互作用和猝灭无序相互作用引起的无带隙双外尔费米子和三外尔费米子的低能行为。发现任意弱障碍
The low-energy behaviors of gapless double- and triple-Weyl fermions caused by the interplay of long-range Coulomb interaction and quenched disorder are studied by performing a renormalization group analysis. It is found that an arbitrarily weak disorder
