In-Medium Mixing and the Phase Structure of QCD — •Fabian Rennecke1, Lorenz von Smekal1, and Maximilian Haensch2 — 1Justus-Liebig-Universität Giessen, Institut für Theoretische Physik — 2Ludwig-Maximilians-Universität München
Interactions in the hot and dense QCD medium give rise to extensive mixing between hadronic and gluonic degrees of freedom. This modifies the analytic structure of the systems and leads to a non-Hermitian mass matrix, with potential far-reaching consequences for the phase diagram. For example, regimes with spatial modulations and instabilities towards inhomogeneous phases can be induced by such a mixing.
