摘要: The presence of the long-range Coulomb force in dense stellar matter implies that total charge cannot be associated with a chemical potential, even if it is conserved quantity. As consequence, analytical properties partition sum are modified, changing order phase transitions and affecting possible occurrence critical behaviors. peculiar thermodynamic this system can understood introducing model Hamiltonian where each independently neutralized by uniform background opposite charge. Some consequences on characteristics mixed-phase structures neutron star crusts supernova cores discussed.
