  During the last decade, density function theory (DFT) in its static and
dynamic time dependent forms, has emerged as a powerful tool to describe the
structure and dynamics of doped liquid helium and droplets. In this review, we
summarize the activity carried out in this field within the DFT framework since
the publication of the previous review article on this subject [M. Barranco et
al., J. Low Temp. Phys. 142, 1 (2006)]. Furthermore, a comprehensive
presentation of the actual implementations of helium DFT is given, which have
not been discussed in the individual articles or are scattered in the existing
literature. This is an Accepted Manuscript of an article published on August 2,
2017 by Taylor & Francis Group in Int. Rev. Phys. Chem. 36, 621 (2017),
