The nuclear liquid–gas phase transition within Fermionic Molecular Dynamics
نویسنده
چکیده
The time evolution of excited nuclei, which are in equilibrium with the surrounding vapour, is investigated. It is shown that the finite nuclear systems undergo a first oder phase transition. The caloric curve is presented for excited O, Mg, Al and Ca and the critical temperature is estimated for O. PACS: 24.10.Cn, 02.70.Ns, 05.30.-d, 05.30.Fk, 05.60.+w, 05.70.Fh

Simulations in Fermionic Molecular Dynamics simulations show, however, that even small systems exhibit all features of a phase transition, provided the total energy of the system can be determined well enough for each member of the statistical ensemble. The results are compared to the caloric curve deduced for finite nuclei by the ALADIN collaboration. The investigation of the equation of state...

Abstract: Nuclear matter within the liquid-gas phase transition region is inNuclear matter within the liquid-gas phase transition region is investigated in a mean-field two-component Fermi-gas model. Following largely analytic considerations, it is shown that: (1) Due to density dependence of asymmetry energy, some of the neutron excess from the high-density phase could be expelled into the low...
متن کاملDiffusive Dynamicsof Binary Lennard-Jones Liquid in the Presence of Gold Nanoparticle: A Mode Coupling Theory Analysis
Molecular dynamics simulation has been performed to analyze the effect of the presence of gold nanoparticle on dynamics of Kob-Anderson binary Lennard-Jones (BLJ) mixture upon supercooling within the framework of the mode coupling theory of the dynamic glass transition. The presence of gold nanoparticle has a direct effect on the liquid structure and causes the peaks of the radial distribution ...
متن کاملIsospin and Momentum Dependence of Liquid-gas Phase Transition in Hot Asymmetric Nuclear Matter
The liquid-gas phase transition in hot neutron-rich nuclear matter is investigated within a self-consistent thermal model using different interactions with or without isospin and/or momentum dependence. The boundary of the phase-coexistence region is shown to be sensitive to the density dependence of the nuclear symmetry energy as well as the isospin and momentum dependence of the nuclear inter...
