TL;DR: This work proposes the existence of a previously overlooked type of Weyl fermion that emerges at the boundary between electron and hole pockets in a new phase of matter and discovers a type-II Weyl point, which is still a protected crossing, but appears at the contact of electron and Hole pockets in type- II Weyl semimetals.

TL;DR: Wannier90 as mentioned in this paper is an open-source computer program for calculating maximally-localised Wannier functions (MLWFs) from a set of Bloch states, which is interfaced to many widely used electronic-structure codes thanks to its independence from the basis sets representing these BLoch states.

TL;DR: With no strain, the number of observable surface Fermi arcs in this material is 2-the smallest number of arcs consistent with time-reversal symmetry, opening a wide range of possible experimental realizations of different topological semimetal phases.

TL;DR: The Z2Pack software package as mentioned in this paper is suitable for high-throughput screening of materials databases for compounds with nontrivial topologies, which can be used to identify topological materials optimal for experimental probes.
