Two-flavor condensates in chiral dynamics: temperature and isospin density effects

Abstract

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 give an additional insight into the condensed-pion phase transition, that occurs basically when |\mui|>m_\pi, being |\mui| the isospin chemical potential. Calculations are done in both phases, showing a good agreement with lattice results for such condensates.Comment: 9 pages, 10 figure
