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 ...
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 ...
The ferroelectric photo ground state of SrTiO3: Cavity materials engineering
(National Academy of Sciences, 2021-08-03)
Optical cavities confine light on a small region in space, which can result in a strong coupling of light with materials inside the cavity. This gives rise to new states where quantum fluctuations of light and matter can ...
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 ...
