Finite-Temperature Gluon Condensate with Renormalization Group Flow Equations

B. -J. Schaefer, O. Bohr, J. Wambach

Within a self-consistent proper-time Renormalization Group (RG) approach we investigate an effective QCD trace anomaly realization with dilatons and determine the finite-temperatur…

Renormalization Group Flow Equations For The Scalar O(N) Theory

B. -J. Schaefer, O. Bohr, J. Wambach

Self-consistent new renormalization group flow equations for an O(N)-symmetric scalar theory are approximated in next-to-leading order of the derivative expansion. The Wilson-Fishe…

Renormalization Group Flow Equations and the Phase Transition in O(N)-models

O. Bohr, B. -J. Schaefer, J. Wambach

We derive and solve flow equations for a general O(N)-symmetric effective potential including wavefunction renormalization corrections combined with a heat-kernel regularization. W…

Flow Equations and the Chiral Phase Transition

B. -J. Schaefer, O. Bohr, J. Wambach

Flow equations for an O(N)-symmetric effective potential are discussed and solved for the finite temperature case. The model is investigated at the critical point and critical expo…

The Octet of Goldstone-Bosons in the SU(3) Linear sigma Model in the QRPA

Z. Aouissat, O. Bohr, J. Wambach.

A symmetry conserving, non-perturbative treatment based on a variational squeezed vacuum state in conjunction with a well-defined class of RPA fluctuations is applied to the SU(3)…
