Goldstone theorem at finite temperature and density

Physical Review D, 1987
A simple proof of the thermal Goldstone theorem is given which is independent of any of the technical devices usually used to incorporate the Kubo-Martin-Schwinger condition into relativistic thermal field theories. A thermal version of the Schwinger action principle is pointed out as a means of obtaining Ward-Takahashi identities under the same ...

Finite-temperature spectral density for the Anderson model

Physical Review B, 1987
Spectral density of local single-particle excitations for the nondegenerate single-impurity Anderson model is calculated for various values of U/\ensuremath{\pi}\ensuremath{\Delta}, ${n}_{f}^{0}$\ensuremath{\equiv}${n}_{f}$(T=0), and T, using the finite-T perturbation theory with U/\ensuremath{\pi}\ensuremath{\Delta} as the expansion parameter and the ...

Finite-temperature and -density renormalization effects in QED

Physical Review D, 1987
An earlier work on finite-temperature renormalization and radiative corrections in QED is generalized to incorporate finite-density effects.

Pion decay constant at finite temperature and density

Physical Review D, 1990
The pion decay constant and the fermionic bilinear condensate at finite temperature and density are evaluated in the whole region of broken chirality by using the composite-operator approach to QCD. The critical exponents around the tricritical point (separating first-order from second-order phase transitions) are determined by general thermodynamical ...

QCD at Finite Temperature and Baryon Number Density

1986
We discuss the status of Monte Carlo simulations for the thermodynamics of QCD. Recent results for pure SU(N) gauge theories at finite temperature and the influence of dynamical fermions on the phase structure at finite temperature as well as problems related to the introduction of non-zero chemical potentials are analyzed.
