On meson spectral functions at high temperature and nonzero momentum
Gert Aarts, Simon Hands, Seyong Kim +1
In the high-temperature phase of QCD meson spectral functions at nonzero momentum are expected to have a nontrivial and interesting structure. In order to provide a reference point…
Transport coefficients and the 2PI effective action in the large N limit
Gert Aarts, Jose M. Martinez Resco
We discuss the computation of transport coefficients in large N_f QCD and the O(N) model for massive particles. The calculation is organized using the 1/N expansion of the 2PI effe…
Shear Viscosity in the O(N) Model
Gert Aarts, Jose M. Martinez Resco
We compute the shear viscosity in the O(N) model at first nontrivial order in the large N expansion. The calculation is organized using the 1/N expansion of the 2PI effective actio…
Transport coefficients and quantum fields
Gert Aarts, Jose M. Martinez Resco
Various aspects of transport coefficients in quantum field theory are reviewed. We describe recent progress in the calculation of transport coefficients in hot gauge theories using…
Transport coefficients from the lattice?
Gert Aarts, Jose M. Martinez Resco
The prospects of extracting transport coefficients from euclidean lattice simulations are discussed. Some general comments on the reconstruction of spectral functions using the Max…
Ward identity and electrical conductivity in hot QED
Gert Aarts, J. M. Martinez Resco
We study the Ward identity for the effective photon-electron vertex summing the ladder diagrams contributing to the electrical conductivity in hot QED at leading logarithmic order.…
