Spinodal amplification of density fluctuations in fluid-dynamical simulations of relativistic nuclear collisions — •Jan Steinheimer1, Jorgen Randrup2, and Volker Koch2 — 1Frankfurt Institute for Advanced Studies, Frankfurt am Main, Germany — 2Lawrence Berkeley National Laboratory, Berkeley, USA
I will present work based on extending a previously developed two-phase equation of state, which for the first time allows simulating head-on relativistic lead-lead collisions, in the presence of a mechanically unstable phase region due to the first order deconfinement phase transition. For collision energies that bring the bulk of the system into the mechanically unstable spinodal region of the phase diagram, the density irregularities are being amplified significantly. The resulting density clumping may be exploited as a signal of the phase transition. I will discuss several observables, like nuclei production, radial correlations and di-lepton production, and their sensitivity on the observed density clumping.
