Time-reversal invariant realization of the Weyl semimetal phase
Time-reversal invariant realization of the Weyl semimetal phase
We propose a realization of the Weyl semimetal phase that is invariant under time reversal and occurs due to broken inversion symmetry. We consider both a simple superlattice model and a more realistic tight-binding model describing an experimentally reasonable HgTe/CdTe multilayer structure. The two models have the same underlying symmetry, …
