Renormalization group methods and the 2PI effective action
M. E. Carrington, Wei-Jie Fu, D. Pickering +1
We consider a symmetric scalar theory with quartic coupling in 4-dimensions and compare the standard 2PI calculation with a modified version which uses a functional renormalization…
4-point vertices from the 2PI and 4PI Effective Actions
M. E. Carrington, Wei-Jie Fu, P. Mikula +1
We consider a symmetric scalar theory with quartic coupling in 2- and 3-dimensions and compare the self-consistent 4-point vertex obtained from the 4PI effective action with the Be…
Bethe-Salpeter Equations from the 4PI effective action
M. E. Carrington, WeiJie Fu, T. Fugleberg +2
In this paper we derive a hierarchy of integral equations from the 4PI effective action which have the form of Bethe-Salpeter equations. We show that, together with the equation of…
The fermion mass at next-to-leading order in the HTL effective theory
M. E. Carrington, A. Gynther, D. Pickering
The calculation of the real part of a quasi-particle dispersion relation at next-to-leading order in the hard thermal loop effective theory is a very difficult problem. Even though…
Real time statistical field theory
M. E. Carrington, T. Fugleberg, D. S. Irvine +1
We have written a {\it Mathematica} program that calculates the integrand corresponding to any amplitude in the closed-time-path formulation of real time statistical field theory.…
Dielectric Functions and Dispersion Relations of Ultra-Relativistic Plasmas with Collisions
M. E. Carrington, T. Fugleberg, D. Pickering +1
In the present paper we calculate the dielectric functions of an ultra-relativistic plasma, such as an electron-positron or a quark-gluon plasma. We use classical transport theory…
