Ultrafast Spin Injection in Graphene via Dynamical Carrier Filtering at Transition Metal Dichalcogenide Interfaces
Shunsuke Yamada, Arqum Hashmi, Tomohito Otobe
We report a real-time first-principles study of ultrafast spin injection in a WSe-graphene heterobilayer under circularly polarized laser irradiation, using time-dependent dens…

Ultrafast Optical Control of Multi-Valley States in 2D SnS
Arqum Hashmi, M. Umar Farooq, Mizuki Tani +3
We theoretically study the ultrafast optical control of multiple valley states in two-dimensional (2D) tin sulfide (SnS) monolayers, a member of the layered group-IV monochalcogeni…
