Instanton-anti-instanton molecule with non-zero-modes of quarks included

A straightforward algebraic derivation is carried out of light quark propagator and effective action in the instanton-anti-instanton molecule. Exact expressions are obtained which contain contributions of all quark modes. Possible implications of the results include chiral phase transition and corre...
