Non-Markovian effects on the dynamics of bubble growth in hot asymmetric nuclear matter Academic Article uri icon


  • We study the conditions for the generation and the dynamical evolution of embryonic overcritical vapor bubbles in an overheated asymmetric nuclear matter. We show that the Fermi-surface distortion and memory effects significantly hinder the growth of the bubbles. Moreover, the growth of the bubble is accompanied by characteristic oscillations of its radius R. The characteristic energy E, the damping parameter , and the instability growth rate parameter , depend on the relaxation time . The characteristic oscillations disappear in the short relaxation time limit 0. Our approach ignores the fluctuations of the particle numbers in the bubble region and the finite diffuse layer of the bubble. The minimum size of the critical radius R* for which our approach applies is determined by the condition a/R*1, where a= 0.5-1 fm is the temperature-dependent surface thickness of the bubble.
