6. Hybrid fluid models from mutual effective metric couplings / Kurkela, Aleksi ; Mukhopadhyay, Ayan ; Preis, Florian ; Rebhan, Anton ; et al
Motivated by a semi-holographic approach to the dynamics of quark-gluon plasma which combines holographic and perturbative descriptions of a strongly coupled infrared and a more weakly coupled ultraviolet sector, we construct a hybrid two-fluid model where interactions between its two sectors are encoded by their effective metric backgrounds, which are determined mutually by their energy-momentum tensors.
