Threefold Fermions, Weyl Points, and Superconductivity in the Mirror Symmetry Lacking Semiconductor TlCd2Te4
The topological phase transition and exotic quasiparticles in materials have attracted Charging much attention because of their potential in spintronics and mimic of elementary particles.Especially, great research interest has been paid to search for the Weyl fermions in solid-state physics.By using first-principles calculations, we predict that th
