  1. Fluctuating ground-state occupation number for trapped BEC Jürgen Bosse Freie Universität Berlin Panjab University, Chandigarh 3rd March, 2014

  2. Overview • Introduction • GCE unknowns: N0, dN0, etc. • Calculate N0 for trapped bosons within TDL assuming fixed N • Calculate corresponding dN0 • Plots of N0, f0, and f1 needed for HFA

  3. N=200 N=2000

  4. Summary and Outlook • TDL and SCA agree for N>>1 • It is essential to consistently determine Tc • Restricting to fixed N does not describe the photon • BEC experiment correctly. The „grand-canonical“ reservoir • needs a more realistic description e.g. the one given by • Weitz group. • Fixing N will result in small fluctuation corrections in HFA.
