Connected Green function approach to ground state symmetry breaking in -theory
J. M. Haeuser, W. Cassing, A. Peter +1
Using the cluster expansions for n-point Green functions we derive a closed set of dynamical equations of motion for connected equal-time Green functions by neglecting all connecte…

Two-Body Correlations in Pionic Systems
J. M. Haeuser, W. Cassing, A. Peter
In close analogy to fermionic many-body theory the truncation of the bosonic BBGKY density matrix hierarchy on the two-body level leads to a coupled set of nonlinear equations of m…
