SALMON 2.3: Implementation of divide-and-conquer ground-state initialization for large-scale real-time TDDFT
Shunsuke Yamada, Tomohito Otobe
In large-scale real-time time-dependent density functional theory (TDDFT), preparing the ground-state electronic structure can be more expensive than the subsequent time propagatio…
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…
Electron Excitation Probability in Dielectrics under Two-color Intense Laser Fields
Mizuki Tani, Kenichi L. Ishikawa, Tomohito Otobe
Two-color laser fields offer significantly enhanced control over electron excitation dynamics under ultrashort intense laser pulses compared to monochromatic fields. However, their…
SALMON VR: Visualizing Light-Matter Dynamics
Tomohito Otobe, Tatsuya Ogusu, Mizuki Tani +1
This study presents SALMON VR, a visualization program designed to visualize the time evolution of electronic density changes and vector potentials in virtual reality (VR) space. T…
Maxwell-Vlasov-Uehling-Uhlenbeck (VUU) Simulation for Coupled Laser-Electron Dynamics in a Metal Irradiated by Ultrashort Intense Laser Pulses
Mizuki Tani, Tomohito Otobe, Yasushi Shinohara +1
The description of electron-electron scattering presents challenges in the microscopic modeling of the interaction of ultrashort intense laser pulses with solids. We extend the sem…
