Investigation of Dephasing In an Open Quantum System under Chaotic Influence via a Fractional Kohn-Sham Scheme

In most investigations involving computationally intense many-electron systems, timedependent density functional theory (TDDFT) is the most commonly used approach. This is due to its practical utility, computational efficiency and accuracy . TDDFT has been successfully employed to a vast amount of problems involving such systems to ascertain and understand their real-time dynamics. For instance, TDDFT has been applied in fields such as photochemical dynamics for the computation of the valence electron excitation energies in large chemical compounds. Besides, TDDFT has also been employed to study characteristics of electronic interactions with cavity photons fields under the influence of quantized electromagnetic fields. In addition, TDDFT has been implemented extensively in studies involving electron-phonon coupling in single molecular transport 9, .
