Ward Identities in Non-equilibrium QED
M. E. Carrington, Hou Defu, Markus H. Thoma
We verify the QED Ward identity for the two- and three -point functions at non-equilibrium in the HTL limit. We use the Keldysh formalism of real time finite temperature field theo…
Convergence properties of the equal-time connected Green function approach for temporal gauge SU(2)_{2+1} Yang-Mills theory
J. M. Hauser, W. Cassing, S. Leupold +1
The hierarchy of equations of motion for equal-time Green functions in temporal gauge SU(N) Yang-Mills theory is truncated using an expansion in terms of connected Green functions.…
Convergence properties of the cluster expansion for equal-time Green functions in scalar theories
A. Peter, W. Cassing, J. M. Hauser +1
We investigate the convergence properties of the cluster expansion of equal-time Green functions in scalar theories with quartic self-coupling in (0+1), (1+1), and (2+1) space-time…
Cluster Expansion Approach to the Effective Potential in -Theory
Andreas Peter, Joern M. Haeuser, Markus H. Thoma +1
We apply a truncated set of dynamical equations of motion for connected equal-time Green functions up to the 4-point level to the investigation of spontaneous ground state symmetry…
