Fluctuation Induced Critical Behavior at Non-Zero Temperature and Chemical Potential
K. Splittorff, J. T. Lenaghan, J. Wirstam
We discuss phase transitions in relativistic systems as a function of both chemical potential and temperature. The presence of a chemical potential explicitly breaks Lorentz invari…
Melting the Diquark Condensate in Two-Color QCD: A Renormalization Group Analysis
J. Wirstam, J. T. Lenaghan, K. Splittorff
We use a Landau theory and the epsilon expansion to study the superfluid phase transition of two-color QCD at nonzero temperature, T, and baryonic chemical potential, mu. At low T,…
One-Loop QCD Corrections to the Thermal Wilson Line Model
J. Wirstam
We calculate the time independent four-point function in high temperature (T) QCD and obtain the leading momentum dependent terms. Furthermore, we relate these derivative interacti…
Hard Thermal Loops and Beyond in the Finite Temperature World-Line Formulation of QED
R. Venugopalan, J. Wirstam
We derive the hard thermal loop action for soft electromagnetic fields in the finite temperature world-line formulation at imaginary time, by first integrating out the hard fermion…
Chiral Symmetry in Two-Color QCD at Finite Temperature
J. Wirstam
We study the chiral symmetry in two-color QCD with N massless flavors at finite temperature, using an effective theory. For the gauge group SU(2), the chiral symmetry is enlarged t…
Minding one's P's and Q's : from the one loop effective action in quantum field theory to classical transport theory
Jamal Jalilian-Marian, Sangyong Jeon, Raju Venugopalan +1
The one loop effective action in quantum field theory can be expressed as a quantum mechanical path integral over world lines, with internal symmetries represented by Grassmanian v…
Thermal Effects on the Low Energy N=2 SUSY Yang-Mills Theory
J. Wirstam
Using the low energy effective action of the N=2 supersymmetric SU(2) Yang-Mills theory we calculate the free energy at finite temperature, both in the semiclassical region and in…
Thermal Dileptons from a Nonperturbative Quark-Gluon Phase
C. -H. Lee, J. Wirstam, I. Zahed +1
Assuming that gluon condensates are important even above the deconfining phase transition, we develop a model for the dilepton yield from a quark gluon plasma. Using a simple fire…
Nonperturbative SUSY Correlators at Finite Temperature
J. Grundberg, J. Wirstam
We calculate finite temperature effects on a correlation function in the two dimensional supersymmetric nonlinear O(3) sigma model. The correlation function violates chiral symmetr…
Real Time Correlators in Hot (2+1)d QCD
T. H. Hansson, J. Wirstam, I. Zahed
We use dimensional reduction techniques to relate real time finite T correlation functions in (2+1) dimensional QCD to bound state parameters in a generalized 't Hooft model with a…
