This will be an introduction to density-functional theory, starting from the founding Hohenberg-Kohn and Kohn-Sham theorems to more advanced problems. In particular, we will discuss the history of the development of exchange-correlation functionals, and the availability of such functionals for the study of different physical systems.
I will discuss the basics and recent developments in the field of (time-independent) ensemble density-functional theory for neutral and charged electronic excited states.
Excited-state dynamics is at the heart of Photophysics and Photochemistry. Nonadiabatic transitions are induced by the strong coupling between electronic dynamics and the ultrafast motion of the nuclei, and are observed in phenomena such as photosynthesis, photovoltaics, and exciton transport in π-conjugated complexes. An essential part of the research efforts in these fields is directed...
I will present a meta-modeling of the equation of state for the description of nuclear matter, and its application to neutron stars, where the density can reach several times the saturation density of atomic nuclei (the average density of nuclei). This equation of state is based on the extrapolation of our knowledge in nuclear physics around saturation density, towards high density, encoded in...
