Thermodynamics of two-flavor isospin-asymmetric superfluid quark matter at next-to-leading order
Tim Rehberg-Juditzky, Andreas Geißel, Jens Braun
We study quark matter at high isospin asymmetry in the limit of vanishing baryon density, a state of matter governed by the condensation of charged pions. In the weak-coupling limi…
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…
Subtleties in the calculation of correlation functions for hot and dense systems
Sebastian Töpfel, Andreas Geißel, 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,…
Pressure and speed of sound in two-flavor color-superconducting quark matter at next-to-leading order
Andreas Geißel, Tyler Gorda, Jens Braun
Deconfined quark matter at asymptotically high densities is weakly coupled, due to the asymptotic freedom of Quantum Chromodynamics. In this weak-coupling regime, bulk thermodynami…
Soft modes in hot QCD matter
Jens Braun, Yong-rui Chen, Wei-jie Fu +9
The chiral crossover of QCD at finite temperature and vanishing baryon density turns into a second order phase transition if lighter than physical quark masses are considered. If t…
