Ab initio insights on the ultrafast strong-field dynamics of anatase TiO

Sruthil Lal S. B, Lokamani, Kushal Ramakrishna +5

Electron dynamics of anatase TiO under the influence of ultrashort and intense laser field is studied using the real-time time-dependent density functional theory (TDDFT). Our…
