95. Hamiltonian Approach to QCD in Coulomb gauge-from the vacuum to finite temperatures

Hugo Reinhardt (Universität Tübingen)

Section A: Vacuum Structure and Confinement

I will review recent results obtained within the Hamiltonian approach to QCD. I will focus on the description of the deconfinement phase transition by compactifying one spatial dimension.

143. A covariant variational approach to Yang-Mills theory

Section A: Vacuum Structure and Confinement

We investigate the low-order Green's functions of *SU(N)* Yang-Mills theory in Landau gauge, using a covariant variational principle based on the effective action formalism. Employing an approximation to the Faddeev-Popov determinant established previously in the Hamiltonian approach in Coulomb gauge leads to a closed and renormalizable set of integral equations for the ghost and...

136. Dyson--Schwinger Equations of Hamiltonian Quantum Chromodynamics

Section A: Vacuum Structure and Confinement

The general method for treating non-Gaussian wave functionals in the Hamiltonian formulation of a quantum field theory, which was previously proposed and developed for Yang-Mills theory in Coulomb gauge, is generalized to full QCD. Exploiting Dyson-Schwinger equation techniques, we express the various $n$-point functions, needed in expectation values of observables like the Hamiltonian, in...
