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 ...
How Circular Dichroism in Time and Angle-Resolved Photoemission Can Be Used to Spectroscopically Detect Transient Topological States in Graphene
(American Physical Society, 2020-10-19)
Pumping graphene with circularly polarized light is the archetype of light-tailoring topological bands. Realizing the induced Floquet-Chern-insulator state and demonstrating clear experimental evidence for its topological ...
Octopus, a computational framework for exploring light-driven phenomena and quantum dynamics in extended and finite system
(American Institute of Physics, 2020)
Over the last few years, extraordinary advances in experimental and theoretical tools have allowed us to monitor and control matter at short time and atomic scales with a high degree of precision. An appealing and challenging ...
