Chapman-Enskog expansion of the Boltzmann equation and its diagrammatic interpretation
M. E. Carrington, Hou Defu, R. Kobes
We perform a Chapman-Enskog expansion of the Boltzmann equation keeping up to quadratic contributions. We obtain a generalized nonlinear Kubo formula, and a set of integral equatio…
Infrared behaviour of the pressure in gϕ^3 theory in 6 dimensions
M. E. Carrington, T. J. Hammond, R. Kobes
In an earlier paper Almeida and Frenkel considered the calculation of the pressure in gϕ^3 theory in 6 dimensions via the Schwinger--Dyson equation. They found, under certain appro…
A General Expression for Symmetry Factors of Feynman Diagrams
C. D. Palmer, M. E. Carrington
The calculation of the symmetry factor corresponding to a given Feynman diagram is well known to be a tedious problem. We have derived a simple formula for these symmetry factors.…
A Diagrammatic Interpretation of the Boltzmann Equation
M. E. Carrington, Hou Defu, R. Kobes
We study nonlinear response in weakly coupled nonequilibrium theory in the context of both classical transport theory and real time quantum field theory, based on a generaliz…
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…
Nonlinear Response from Transport Theory and Quantum Field Theory at Finite Temperature
M. E. Carrington, Hou Defu, R. Kobes
We study nonlinear response in weakly coupled hot theory. We obtain an expression for a quadratic shear viscous response coefficient using two different formalisms: transport…
