Multi-scattering processes and spectral properties of low-energy QCD
Konrad Kockler, Jan M. Pawlowski, Franz R. Sattler +2
We compute quark and meson spectral functions in low-energy QCD, including all-order scatterings and decays of pions and the scalar -mode. For low energies the gluons decouple a…
Self-consistent graviton spectral function in Lorentzian quantum gravity
Jan M. Pawlowski, Manuel Reichert, Jonas Wessely
We present the first fully self-consistent computation of the graviton spectral function in quantum gravity, using the spectral renormalisation group for gravity put forward in arX…
Critical scaling for spectral functions
Konrad Kockler, Jan M. Pawlowski, Jonas Wessely
We study real-time scalar -theory in 2+1 dimensions near criticality. Specifically, we compute the single-particle spectral function and that of the -channel four-point fun…
The causal structure of the quark propagator
Jan M. Pawlowski, Jonas Wessely
We study the causal structure of the quark propagator with the spectral DSE. The spectral gap equation is solved with the input of the spectral representation of the gluon and a ca…
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…
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…
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…
