WebOct 20, 2024 · Real-time time-dependent density functional theory (RT-TDDFT) is an attractive tool to model quantum dynamics by real-time propagation without the linear response approximation. WebJul 6, 2024 · In this work, to investigate the coherent or disordered manner of atomic motion, we have utilized our newly developed real-time time-dependent density functional theory (rt-TDDFT) algorithm (6, 27, 28) to simulate the PIPT in VO 2. We show that the phase transition is in atomic disordering with a timescale of ∼200 fs at low laser fluence.
