Color superconductivity under neutron-star conditions at next-to-leading order
Andreas Geißel, Tyler Gorda, Jens Braun
The equation of state of deconfined strongly interacting matter at high densities remains an open question, with effects from quark pairing in the preferred color-flavor-locked (CF…

Juggling with Tensor Bases in Functional Approaches
Jens Braun, Andreas Geißel, Jan M. Pawlowski +2
Systematic expansion schemes in functional approaches require the inclusion of higher order vertices. These vertices are expanded in independent tensor bases with a rapidly increas…

Phase structure of quark matter and in-medium properties of mesons from Callan-Symanzik flows
Sebastian Töpfel, Jan M. Pawlowski, Jens Braun
We compute meson spectral functions at finite temperature and density in the quark-meson model, supplemented with a computation of the phase diagram. In particular, we provide a de…
