Isotropization of a rotating and longitudinally expanding scalar system
Margaret E. Carrington, Gabor Kunstatter, Christopher Phillips +1
We present numerical simulations for the evolution of an expanding system of massless scalar fields with quartic coupling. By setting a rotating, non-isotropic initial configuratio…
A Non-Equilibrium Approach To Holographic Superconductors Using Gradient Flow
Paul Mikula, Margaret E. Carrington, Gabor Kunstatter
We study a charged scalar field in a bulk 3+1 dimensional anti-deSitter spacetime with a planar black hole background metric. Through the AdS/CFT correspondence this is equivalent…
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…
Smooth and sharp creation of a pointlike source for a -dimensional quantum field
L. J. Zhou, Margaret E. Carrington, Gabor Kunstatter +1
We analyse the smooth and sharp creation of a pointlike source for a quantised massless scalar field in -dimensional Minkowski spacetime, as a model for the breakdown of cor…
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…
