Non-Fermi Liquid Behaviour, the BRST Identity in the Dense Quark-Gluon Plasma and Color Superconductivity
William E. Brown, James T. Liu, Hai-cang Ren
At sufficiently high baryon densities, the physics of a dense quark-gluon plasma may be investigated through the tools of perturbative QCD. This approach has recently been successf…
The Transition Temperature to the Superconducting Phase of QCD at High Baryon Density
William E. Brown, James T. Liu, Hai-cang Ren
Recent interest in the study of color superconductivity has focused on the regime of high baryon density where perturbative QCD may be employed. Based on the dominant one-gluon-exc…
Gauge Invariant Variational Approach with Fermions: the Schwinger Model
William E. Brown, Juan P. Garrahan, Ian I. Kogan +1
We extend the gauge invariant variational approach of Phys. Rev. D52 (1995) 3719, hep-th/9408081, to theories with fermions. As the simplest example we consider the massless Schwin…
On the Perturbative Nature of Color Superconductivity
William E. Brown, James T. Liu, Hai-cang Ren
Color superconductivity is a possible phase of high density QCD. We present a systematic derivation of the transition temperature, T_C, from the QCD Lagrangian through study of the…
Instantons and the QCD Vacuum Wavefunctional
William E. Brown, Juan P. Garrahan, Ian I. Kogan +1
We analyze the instanton transitions in the framework of the gauge invariant variational calculation in the pure Yang-Mills theory. Instantons are identified with the saddle points…
Equivalence of the Beta-function of the Variational Approach to that of QCD
William E. Brown
The variational ansatz for the ground state wavefunctional of QCD is found to capture the anti-screening behaviour that contributes the dominant `-4' to the beta-function and leads…
