Application of Renormalization Group Techniques to a Homogeneous Bose Gas at Finite Temperature
Jens O. Andersen, Michael Strickland
A homogeneous Bose gas is investigated at finite temperature using renormalization group techniques. A non--perturbative flow equation for the effective potential is derived using…
Non-Perturbative QED and QCD at Finite Temperature
Michael Strickland
We present results of numerical solutions of Schwinger-Dyson equations for the finite-temperature quark and electron propagators. It is shown that both strongly coupled QED and QCD…
Critical Behaviour of a Homogeneous Bose Gas at Finite Temperature
Jens O. Andersen, Michael Strickland
A homogeneous non-relativistic Bose gas is investigated at finite temperature using renormalization group methods. The phase transition is shown to be second order and the effectiv…
Scheme Independence of Blocking Transformation in Finite-Temperature Renormalization Group
Michael Strickland, Sen-Ben Liao
The finite-temperature renormalization group is formulated via the Wilson-Kadanoff blocking transformation. Momentum modes and the Matsubara frequencies are coupled by constraints…
