Color superconductivity under neutron-star conditions at next-to-leading order
Andreas GeiÃel, 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 GeiÃel, 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…

Subtleties in the calculation of correlation functions for hot and dense systems
Sebastian Töpfel, Andreas GeiÃel, Jens Braun
We discuss subtleties in the calculation of loop integrals in studies of hot and dense systems as they appear in both perturbative and non-perturbative approaches. To be specific,…
