Ghost spectral function from the spectral Dyson-Schwinger equation
Jan Horak, Joannis Papavassiliou, Jan M. Pawlowski +1
We compute the ghost spectral function in Yang-Mills theory by solving the corresponding Dyson-Schwinger equation for a given input gluon spectral function. The results encompass b…
Shocks and quark-meson scatterings at large density
Eduardo Grossi, Friederike J. Ihssen, Jan M. Pawlowski +1
We discuss the phase structure of the two-flavour quark-meson model including quantum, thermal, density and critical fluctuations with the functional renormalisation group. This st…
Spectral functions in the -theory from the spectral DSE
Jan Horak, Jan M. Pawlowski, Nicolas Wink
We develop a non-perturbative functional framework for computing real-time correlation functions in strongly correlated systems. The framework is based on the spectral representati…
Dynamics of critical fluctuations: Theory -- phenomenology -- heavy-ion collisions
M. Bluhm, M. Nahrgang, A. Kalweit +27
This report summarizes the presentations and discussions during the Rapid Reaction Task Force "Dynamics of critical fluctuations: Theory -- phenomenology -- heavy-ion collisions",…
Spectral Reconstruction with Deep Neural Networks
Lukas Kades, Jan M. Pawlowski, Alexander Rothkopf +5
We explore artificial neural networks as a tool for the reconstruction of spectral functions from imaginary time Green's functions, a classic ill-conditioned inverse problem. Our a…
Bound state properties from the Functional Renormalisation Group
Reinhard Alkofer, Axel Maas, Walid Ahmed Mian +4
We discuss an approach for accessing bound state properties, like mass and decay width, of a theory within the functional renormalisation group approach. An important cornerstone i…
