Thermal properties of relativistic Δ-resonance nuclear matter in the relativistic δ-ω-π model

In the present work, the binding energy, pressure, incompressibility, the density and effective mass of nucleon and delta isobar in the relativistic Δ-resonance nuclear matter at finite temperature are studied in the relativistic δ-ω-π model. The one-loop vacuum fluctuation of nucleon and the Δ-isobar is very important to the properties of Δ-resonance nuclear matter, even if at low temperature. The pressure density calculated both in quantum hadrodynamics model and in thermostatistical mechanics is consistent. The density of nucleon ( Δ-isobar) decreases (increases), respectively, for a given baryon density, when temperature increases
