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.
