Model-space Brueckner-Hartree-Fock approach for asymmetric nuclear matter.
The model-space Brueckner-Hartree-Fock (BHF) approach of nuclear matter is extended to asymmetric nuclear matter. The energy per nucleon of bulk nuclear matter is calculated over a wide range of density and asymmetry parameter with both the Reid soft-core and the Paris nucleon-nucleon interactions. The results are compared to those calculated by using the usual BHF approach.

Coulomb instability of hot nuclei in a chiral symmetry model
A chiral symmetry model for nuclear matter is extended to finite temperature and then used to study the Coulomb instability of hot nuclei. The role of the rho meson degree of freedom is discussed. The calculated limiting temperature is compared with the results obtained from other theories and experiments. [S0556-2813(99)05006-2].

Quark-meson coupling model at finite temperature
The quark meson coupling model for nuclear matter is extended to finite temperature. The resulting equation of state is applied to discuss the liquid-gas phase transition in nuclear matter. The calculated critical temperature is compared with those given by the Walecka and other models.

The effect of surface and Coulomb interaction on the liquid–gas phase transition of finite nuclei
By means of the Furnstahl, Serot and Tang's model, the effects of surface tension and Coulomb interaction on the liquid-gas phase transition for finite nuclei are investigated. A limit pressure p(lim) above which the liquid-gas phase transition cannot take place has been found. It is found that comparing to the Coulomb interaction, the contribution of surface tension is dominate in low temperature regions. The binodal surface is also addressed.

Strange hadronic matter in the FST model
The strange hadronic matter with nucleon, Λ-hyperon and Ⅺ-hyperon is studied by using the FST model in a mean-field approximation. The saturation properties and stabilities of the strange hadronic matter are discussed.

Thermodynamical properties of nuclear matter in a model with vector meson self-interaction
The relativistic model with vector meson self-interaction (Bodmer A R 1991 Nuc. Phys. A 526 703) is extended to asymmetric nuclear matter at finite temperature. The extended model is then used to discuss the liquid-gas phase transition in nuclear matter and the Coulomb instability of hot nuclei. It is found that the limiting temperature and the critical temperature depend on the parameter sets of this model considerably. The role the meson plays in asymmetric nuclear matter is also examined.

Hawking radiation of Dirac fields in the (2+1)-dimensional black hole space-time.
By calculating the response function, we study the Hawking radiation of massless Dirac fields in the (2+1)-dimensional black hole geometry. We find that the response function has Planck distributions, with the temperature that agrees with the previous results obtained for the scalar field cases. We also find the Green's functions in (2+1)-dimensional Einstein static universe and anti de-Sitter space.
