Continuum and lattice meson spectral functions at nonzero momentum and high temperature
Gert Aarts, Jose M. Martinez Resco
We analyse discretization effects in the calculation of high-temperature meson spectral functions at nonzero momentum and fermion mass on the lattice. We do so by comparing continu…
Transport coefficients in large N_f gauge theories with massive fermions
Gert Aarts, Jose M. Martinez Resco
We compute the shear viscosity and the electrical conductivity in gauge theories with massive fermions at leading order in the large N_f expansion. The calculation is organized usi…
Transport coefficients from the 2PI effective action
Gert Aarts, Jose M. Martinez Resco
We show that the lowest nontrivial truncation of the two-particle irreducible (2PI) effective action correctly determines transport coefficients in a weak coupling or 1/N expansion…
Transport coefficients, spectral functions and the lattice
Gert Aarts, Jose Maria Martinez Resco
Transport coefficients are determined by the slope of spectral functions of composite operators at zero frequency. We study the spectral function relevant for the shear viscosity f…
