Survival of Floquet-Bloch States in the Presence of Scattering
(American Chemical Society, 2021-06-23)
Floquet theory has spawned many exciting possibilities for electronic structure control with light, with enormous potential for future applications. The experimental demonstration in solids, however, remains largely ...
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 ...
