摘要
At finite baryon chemical potential,the density of a quark matter develops large fluctuations when it undergoes a first-order phase transition.Based on the transport equation derived from the Nambu–Jona-Lasinio(NJL) model,we have studied the density fluctuations in a baryon-rich quark matter that is confined in a finite volume.Allowing the expansion of the quark matter using initial conditions from either a blast wave model or a multiphase transport(AMPT) model,we have further studied the survivability of the density fluctuations as the density and temperature of the quark matter decrease.Possible experimental signatures of the density fluctuations are suggested.
