Glasma properties in small proper time expansion
Margaret E. Carrington, Wade N. Cowie, Bryce T. Friesen +2
In a series of works by two of us, various characteristics of the glasma from the earliest phase of relativistic heavy-ion collisions have been studied using a proper time expansio…
Renormalization of the 4PI effective action using the functional renormalization group
M. E. Carrington, S. A. Friesen, C. D. Phillips +1
Techniques based on -particle irreducible effective actions can be used to study systems where perturbation theory does not apply. The main advantage, relative to other non-pert…
The 2PI effective theory at next-to-leading order using the functional renormalization group
M. E. Carrington, S. A. Friesen, B. A. Meggison +3
We consider a symmetric scalar theory with quartic coupling in 4-dimensions. We show that the 4 loop 2PI calculation can be done using a renormalization group method. The calculati…
The 2PI effective action at four loop order in theory
M. E. Carrington, B. A. Meggison, D. Pickering
It is well known that perturbative pressure calculations show poor convergence. Calculations using a two particle irreducible (2PI) effective action show improved convergence at th…
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…
