WebThe recent proposal of the type-II Weyl semimetal state has attracted significant interest. In this Letter, we propose the concept of the three-dimensional type-II Dirac fermion and theoretically identify this new symmetry-protected topological state in the large family of transition-metal icosagenides, MA_{3} (M=V, Nb, Ta; A=Al, Ga, In). We show that the … WebPrinceton University, Princeton, New Jersey, 08544, USA 10 Division of Physics and Applied Physics, School of Physical and Mathematical Sciences, ...
