A joint publication with Jairo Sinova and Libor Ċ mejkal about the influence of magnetism, strain, and pressure on the band topology of EuCd2As2 has been published in Physical Review B.
They analyze the role of the delicate interplay of Eu magnetism, strain, and pressure on the realization of nontrivial topological phases. For that they invoke a combination of a group theoretical analysis with ab initio density functional theory calculations and uncover a rich phase diagram with various nontrivial topological phases beyond a Weyl semimetallic state, such as axion and topological crystalline insulating phases, and discuss their realization.
