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.…
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…
Far-from-equilibrium dynamics with broken symmetries from the 2PI-1/N expansion
G. Aarts, D. Ahrensmeier, R. Baier +2
We derive the nonequilibrium real-time evolution of an O(N) - invariant scalar quantum field theory in the presence of a nonvanishing expectation value of the quantum field. Using…
