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,…
