Creating stable Floquet–Weyl semimetals by laser-driving of 3D Dirac materials
(Nature Publishing, 2017-01-17)
Tuning and stabilizing topological states, such as Weyl semimetals, Dirac semimetals or topological insulators, is emerging as one of the major topics in materials science. Periodic driving of many-body systems offers a ...
Unraveling materials Berry curvature and Chern numbers from real-time evolution of Bloch states
(Natlacad Sciences, 2019-03-05)
Materials can be classified by the topological character of their electronic structure and, in this perspective, global attributes immune to local deformations have been discussed in terms of Berry curvature and Chern ...
