temperature measurement of a BEC with tunable interaction by in-situ imaging using semi-classical and hartree-fock model — •Pierre Jouve — University of Nottingham UK

Various model of differing complexity can be used to model the density of Bose-Einstein condensate (BEC) in an harmonic trap to extract quantities such as temperature and chemical potential. We present two diff*erent method, the semi-classical thermal cloud and Hartree Fock model. We demonstrate that the Hatree-Fock method leads to more accurate result for temperature of the system close to Tc, the Bose-Einstein condensation temperature transition.
