Abstract
Real-time finite-temperature Green’s-function methods with a normal pair cutoff approximation and an abnormal pair cutoff approximation are applied to the calculation of liquid-gas and superconducting phase transitions of finite nuclear matter. Finite-size effects are found to lead to a sizable reduction of the critical temperature of the liquid-gas phase transition (6 MeV) as compared to the case of infinite nuclear matter. A critical number of nucleons Nc as well as a critical volume Vc are found. Under the condition N<Nc (or V<Vc) the superconducting phase disappears. Dependence of the energy gap for the finite nuclear matter with different sizes is discussed.
