Cosmological particle creation in a hadronic fluid
Neven Bilic, Dijana Tolic
Acoustic perturbations in an expanding hadronic fluid at temperatures below the chiral transition point represent massless pions propagating in curved spacetime geometry. In comovi…

FRW universe in the laboratory
Neven Bilic, Dijana Tolic
We consider an expanding relativistic fluid with spherical symmetry as a model for an analog FRW spacetime. In the framework of relativistic acoustic geometry we demonstrate how to…

Trapped surfaces in a hadronic fluid
Neven Bilic, Dijana Tolic
Pion propagation in a hadronic fluid with a non-homogeneous relativistic flow is studied in terms of the linear sigma model. The wave equation turns out to be equivalent to the equ…
