Hot Scalar Theory in Large N: Bose-Einstein Condensation
Peter Arnold
I review the Bose-Einstein condensation phase transition of dilute gases of cold atoms, for particle theorists acquainted with methods of field theory at finite temperature. I then…
The non-Abelian Debye screening length beyond leading order
Peter Arnold, Laurence G. Yaffe
In quantum electrodynamics, static electric fields are screened at non-zero temperatures by charges in the plasma. The inverse screening length, or Debye mass, may be analyzed in p…
The Three-Loop Free Energy for High-Temperature QED and QCD with Fermions
Peter Arnold, Chengxing Zhai
We compute the free energy density for gauge theories, with fermions, at high temperature and zero chemical potential. Specifically, we analytically compute the free energy through…
The Three-Loop Free Energy for Pure Gauge QCD
Peter Arnold, Chengxing Zhai
We compute the free energy density for pure non-Abelian gauge theory at high temperature and zero chemical potential. The three-loop result to is [a lovely formula. Get th…
On the Analytic Structure of the Self-Energy for Massive Gauge Bosons at Finite Temperature
P. Arnold, P. Bedaque, A. Das +1
We show that the one-loop self-energy at finite temperature has a unique limit as the external momentum {\it if} the loop involves propagators with distinct mass…
