Type-II Symmetry-Protected Topological Dirac Semimetals
... Lorentz symmetry whose analog does not exist in the Standard Model. While this state has been dubbed the type-II Weyl semimetal and predicted in a number of materials, its Dirac counterpart has remained elusive. In this paper, we propose the concept of the three-dimensional type-II Dirac fermion and ...
