Optically driven ultrafast lattice contraction in a topological crystalline insulator
M. H. Berntsen, W. Chen, D. Phuyal +9
The ability to dynamically control topological order remains a central challenge in the exploration of quantum materials. Here, we investigate the lattice and electronic response o…
Floquet dressing of bulk metallic bands in 2H-NbSe2
Cong Li, Qirui Cui, Maciej Dendzik +6
Floquet dressing offers a route to controlling electronic states through periodic optical driving. Its realization in solids has centred primarily on topological-insulator surface…
Ultrafast nonlinear Hall effect in black phosphorus
Maciej Dendzik, Andrea Marini, Samuel Beaulieu +9
The nonlinear Hall effect (NHE) is a recently discovered member of the Hall effect family in which the Hall voltage shows a nonlinear behavior when a transverse electric field is a…
Contrasting electron-phonon interaction between electron- and hole-doped cuprates
Qinda Guo, Ke-Jun Xu, Magnus H. Berntsen +15
Spin- and charge-lattice interactions are potential key factors in the microscopic mechanism of high-temperature superconductivity in cuprates. Although both interactions can drama…
