The invariant factor of the chiral determinant
L. L. Salcedo
The coupling of spin 0 and spin 1 external fields to Dirac fermions defines a theory which displays gauge chiral symmetry. Quantum mechanically, functional integration of the fermi…
Direct construction of the effective action of chiral gauge fermions in the anomalous sector
L. L. Salcedo
The anomaly implies an obstruction to a fully chiral covariant calculation of the effective action in the abnormal parity sector of chiral theories. The standard approach then is t…
Derivative expansion of the heat kernel in curved space
L. L. Salcedo
The heat kernel in curved space-time is computed to fourth order in a strict expansion in the number of covariant derivatives. The computation is made for arbitrary non abelian gau…
The method of covariant symbols in curved space-time
L. L. Salcedo
Diagonal matrix elements of pseudodifferential operators are needed in order to compute effective Lagrangians and currents. For this purpose the method of symbols is often used, wh…
The Polyakov loop and the heat kernel expansion at finite temperature
E. Megias, E. Ruiz Arriola, L. L. Salcedo
The lower order terms of the heat kernel expansion at coincident points are computed in the context of finite temperature quantum field theory for flat space-time and in the presen…
