In terms of the Thomas-Fermi method, we solve the ground state energy of the N-body 1 D harmonically trapped spin-1/2 fermion gas with the attractive δ-function interaction in the limit N →∞.

By fixing N|κ|, this leads to the mean-field approximation of Bose-Einstein condensates with attractive interactions in R^2.展开更多

After a summary of central problems concerning the German health sector and its current challenges, the study design behind the systematic content analysis as well as its criteria are presented. Selected results describe characteristics of expert literature for employer attractiveness in general, the attractiveness of German hospitals as employers (“hospital employer attractiveness” for short) as well as employer attractiveness from a medical doctor’s point of view. For each of these areas, focal points of research and main results are summarized and research gaps are pointed out.展开更多
