Spectral properties and observables in ultracold Fermi gases
Eugen Dizer, Jan Horak, Jan M. Pawlowski
We calculate non-perturbative self-consistent fermionic and bosonic spectral functions of ultra-cold Fermi gases with the spectral functional approach. This approach allows for a d…
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…
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…
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…
Renormalised spectral flows
Jens Braun, Yong-rui Chen, Wei-jie Fu +11
We derive renormalised finite functional flow equations for quantum field theories in real and imaginary time that incorporate scale transformations of the renormalisation conditio…
