Spectral properties of pseudo-scalar mesons through the QCD chiral crossover
Peter Lowdon, Owe Philipsen
We summarise recent progress towards the non-perturbative determination of thermal spectral functions for pseudo-scalar mesons in QCD by exploiting constraints imposed by micro-cau…

Non-perturbative constraints on perturbation theory at finite temperature
Peter Lowdon, Owe Philipsen
It has long been understood that the inclusion of temperature in the perturbative treatment of quantum field theories leads to complications that are not present at zero temperatur…

On the (in)consistency of perturbation theory at finite temperature
Peter Lowdon, Owe Philipsen
A well-known difficulty of perturbative approaches to quantum field theory at finite temperature is the necessity to address theoretical constraints that are not present in the vac…
