Bottomonium at Non-zero Temperature from Lattice Non-relativistic QCD
Gert Aarts, Chris Allton, Seyong Kim +5
The temperature dependence of bottomonium states at temperatures above and below is presented, using non-relativistic dynamics for the bottom quark and full relativistic latt…
Two complex problems on the lattice: transport coefficients and finite chemical potential
Gert Aarts
After a few remarks about the problem of extracting transport coefficients from lattice QCD calculations, I report on recent developments in applying stochastic quantization and co…
Effective convergence of the 2PI-1/N expansion for nonequilibrium quantum fields
Gert Aarts, Nathan Laurie, Anders Tranberg
The 1/N expansion of the two-particle irreducible effective action offers a powerful approach to study quantum field dynamics far from equilibrium. We investigate the effective con…
Thermal effects on slow-roll dynamics
Gert Aarts, Anders Tranberg
A description of the transition from the inflationary epoch to radiation domination requires the understanding of quantum fields out of thermal equilibrium, particle creation and t…
Particle creation and warm inflation
Gert Aarts, Anders Tranberg
During cosmological inflation, it has been suggested that fields coupled to the inflaton can be excited by the slow-rolling inflaton into a quasi-stable non-vacuum state. Within th…
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…
