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…
