The effect of anisotropy on the formation of heavy quarkonium bound states
Margaret E. Carrington, Gabor Kunstatter, Arghya Mukherjee
We study the real part of the static potential of a heavy quark-antiquark system in an anisotropic plasma medium. We use a quasi-particle approach where the collective dynamics of…
2PI effective action and gauge invariance problems
M. E. Carrington, G. Kunstatter, H. Zaraket
The problem of maintaining gauge invariance when truncating the two particle irreducible (2PI) effective action has been studied recently by several authors. Here we give a simple…
Spontaneous Symmetry Breaking for Scalar QED with Non-minimal Chern-Simons Coupling
D. S. Irvine, M. E. Carrington, G. Kunstatter +1
We investigate the two-loop effective potential for both minimally and non-minimally coupled Maxwell-Chern-Simons theories. The non-minimal gauge interaction represents the magneti…
Covariant approach to equilibration in effective field theories
Mark Burgess, Margaret Carrington, Gabor Kunstatter
The equilibration of two coupled reservoirs is studied using a Green function approach which is suitable for future development with the closed time path method. The problem is sol…
Equilibration in an Interacting Field Theory
E. Vaz, M. E. Carrington, R. Kobes +1
We use a combination of perturbation theory and numerical techniques to study the equilibration of two interacting fields which are initially at thermal equilibrium at different te…
Constraint from Lamb Shift and Anomalous Magnetic Moment on Radiatively Induced Lorentz and CPT Violation in Quantum Electrodynamics
W. F. Chen, G. Kunstatter
We investigate the precisely measured anomalous magnetic moment and Lamb shift as tests for the possible existence of the radiatively induced Lorentz and CPT violation effects in q…
Parameterization Invariance and the Resolution of the Unitary Gauge Puzzle
P. F. Kelly, R. Kobes, G. Kunstatter
We examine the calculation of the critical temperature for the restoration of a spontaneously broken symmetry. Motivated by a set of recently developed gauge dependence ident…
