Ground-state properties of trapped Bose-Fermi mixtures: role of exchange-correlation
Alexander P. Albus, Fabrizio Illuminati, Martin Wilkens
We introduce Density Functional Theory for inhomogeneous Bose-Fermi mixtures, derive the associated Kohn-Sham equations, and determine the exchange-correlation energy in local dens…

Thermodynamic identities and particle number fluctuations in weakly interacting Bose--Einstein condensates
Fabrizio Illuminati, Patrick Navez, Martin Wilkens
We derive exact thermodynamic identities relating the average number of condensed atoms and the root-mean-square fluctuations determined in different statistical ensembles for the…
