Time-dependent density functional theory (TDDFT) is a formally exact approach to the time-
dependent electronic many-body problem which is widely used for calculating excitation …

The rapid development of the computational methods based on density functional theory, on
the one hand, and of time-, energy-, and momentum-resolved spectroscopy, on the other …

The origin of charge density waves (CDWs) in TiSe 2 has long been debated, mainly due to
the difficulties in identifying the timescales of the excitonic pairing and electron–phonon …

A fundamental property of a quantum system driven by an external field is that when the field
is turned off the positions of its response frequencies are independent of the time at which …

We calculate the dielectric response of crystalline silicon following irradiation by a high-
intensity laser pulse, modeling the dynamics by the time-dependent Kohn-Sham equations …

We theoretically investigate the dynamical Franz-Keldysh effect in femtosecond time
resolution, that is, the time-dependent modulation of a dielectric function at around the band …

We calculate the energy deposition by very short laser pulses in SiO 2 (α-quartz) with a view
to establishing systematics for predicting damage and nanoparticle production. The …

Energy transfer processes from a high-intensity ultrashort laser pulse to electrons in simple
dielectrics, silicon, diamond, and α-quartz are theoretically investigated by first-principles …

By means of first principles calculations, we compute the effective electron-phonon coupling
constant G 0 governing the electron cooling in photoexcited bismuth. G 0 strongly increases …

The exact exchange-correlation (xc) potential of time-dependent density functional theory
has been shown to have striking features. For example, step and peak features are …
