摘要：
Isospin density and thermal corrections for several condensates are discussed, at the one-loop level, in the frame of chiral dynamics with pionic degrees of freedom. The evolution of such objects gives an additional insight into the condensed-pion phase transition that occurs basically when vertical bar mu(I)vertical bar > m(pi), vertical bar mu(I)vertical bar being the isospin chemical potential. Calculations are done in both phases, showing a good agreement with lattice results for such condensates.
