Out-Of-Equilibrium determination of continuous phase transitions
Matteo Lulli (Tor Vergata Univ.)
In this talk I will introduce a rather recent scaling method allowing to perform the usual equilibrium finite-size scaling analysis for continuous phase transitions in the out-of-equilibrium relaxation regime. Such an approach is most valuable for all those system which show a very slow critical dynamics - i.e. a high value of the dynamic exponent …

In-medium Landau gauge gluon spectral functions from lattice QCD with Nf=2+1+1 dynamical quarks
Dr. Alexander Rothkopf (Institute for Theoretical Physics, University of Bern)
We present our recent study of gluon spectra in lattice QCD at finite temperature . In it we combine recent full QCD simulations with Nf=2+1+1 twisted mass flavors carried out by the tmft collaboration with a novel Bayesian approach to the reconstruction of general spectral functions. This method is directly applicable to gluon correlation functions …

The “Resonances Via Padé” (RVP) Method
Ralf-Arno Tripolt (ECT*, Villazzano (TN))
The RVP method in principle allows to obtain the analytic continuation of a function that is only given in numerical form. It only requires real input in order to reconstruct the underlying function not only along the real axis but also in the complex plane. It is applied to experimental data in order to locate …
