Bound states from the spectral Bethe-Salpeter equation
Gernot Eichmann, Andrés Gómez, Jan Horak +3
We compute the bound state properties of three-dimensional scalar theory in the broken phase. To this end, we extend the recently developed technique of spectral Dyson-Schwin…
Towards quantitative precision for QCD at large densities
Friederike Ihssen, Jan M. Pawlowski, Franz R. Sattler +1
QCD at large density reveals a rich phase structure, ranging from a potential critical end point and inhomogeneous phases or moat regimes to color superconducting ones with competi…
The nuclear liquid-gas transition in QCD
Kenji Fukushima, Jan Horak, Jan M. Pawlowski +2
We estimate the nuclear saturation density and the binding energy in a nuclear liquid from precision data on the coupling of the four-quark scattering vertex in the vector channel,…
Scalar spectral functions from the spectral fRG
Jan Horak, Friederike Ihssen, Jan M. Pawlowski +2
We compute non-perturbative spectral functions in a scalar -theory in three spacetime dimensions via the spectral functional renormalisation group. This approach allows for th…
Numerical RG-time integration of the effective potential: Analysis and Benchmark
Friederike Ihssen, Franz R. Sattler, Nicolas Wink
We investigate the RG-time integration of the effective potential in the functional renormalization group in the presence of spontaneous symmetry breaking and its subsequent convex…
Non-perturbative strong coupling at timelike momenta
Jan Horak, Jan M. Pawlowski, Jonas Turnwald +3
We compute the strong coupling constant of Landau gauge QCD in the full complex momentum plane, both directly and via spectral reconstruction. In particular, we consider the Taylor…
