Lattice QED at Finite Temperature and Finite Density
Communications in Theoretical Physics, 1998In this letter, we apply the variational cumulant expansion (VCE) method to the lattice QED, which has complex action at finite density . The chiral order parameter and the number density at finite temperature are calculated.

NNπ Interaction at Finite Temperature and Finite Density
Chinese Physics Letters, 1993By means of the Matsubara imaginary-time Green's function method, we extend the NNπ interaction to finite-temperature and finite-density by summing bubble diagrams. We find that the effective mass of pion increases but the effective NNπ interaction decreases as the density and/or temperature increase.

Decoupling of the pion at finite temperature and density
Physical Review D, 1987We use the Nambu--Jona-Lasinio model at finite temperature and density to investigate the static and dynamical properties of the pion. Near the chiral phase transition the pion is found to decouple from matter. The relevance of this result for hadronic matter is discussed.

NUCLEAR LEVEL DENSITY AT FINITE TEMPERATURES
International Journal of Modern Physics E, 2006Selfconsistent mean-field calculations have been performed with the SkM* Skyrme force for 140 spherical even-even nuclei at temperatures 0≤T≤4 MeV . Single-particle level densities for this sample of nuclei are determined for various temperatures. The average dependence of the single-particle level density on mass number A and isospin is given and ...

The pion at finite temperature and density
Nuclear Physics A, 1991We review the low-temperature variation in the pion mass with temperature. This dependence follows from explicit chiral symmetry breaking and can be calculated in terms of pionic interactions. We then show that the standard calculation of the density dependence of the pion mass gives only a small increase in this mass with increasing density.

ANOMALIES AT FINITE TEMPERATURE AND DENSITY
International Journal of Modern Physics A, 1994Chiral anomalies for Abelian and non-Abelian quantum field theories at finite temperature and density (FTFD) are analyzed in detail in both imaginary and real time (IT and RT) formalisms. IT and RT triangle diagrams and IT functional methods (à la Fujikawa) are used at FTFD.
