Mass zeros in the one-loop effective actions of QED in 1+1 and 3+1 dimensions
It is known that the one-loop effective action of QED2 is a quadratic in the field strength when the fermion mass is zero: all potential higher order contributions beyond second order vanish. For nonzero fermion mass it is shown that this behavior persists for a general class of fields for at least one value of the fermion mass when the external field’s flux Φ satisfies 0 < |eΦ| < 2π. For QED4 ...
متن کاملDerivative Expansion of the One-loop Effective Action in Qed
The one-loop effective action in QED at zero and finite temperature is obtained by using the worldline approach. The Feynman rules for the perturbative expansion of the action in the number of derivatives are derived. The general structure of the temperature dependent part of the effective action in an arbitrary external inhomogeneous magnetic field is established. The two-derivative term in th...
متن کاملDerivative Expansion for the One - Loop Effective Lagrangian in Qed
The derivative expansion of the one-loop effective Lagrangian in QED 4 is considered. The first term in such an expansion is the famous Schwinger result for a constant electromagnetic field. In this paper we give an explicit expression for the next term containing two derivatives of the field strength F µν. The results are presented for both fermion and scalar electrodynamics. Some possible app...
متن کاملEffective QED actions: Representations, gauge invariance, anomalies, and mass expansions
We analyze and give explicit representations for the effective Abelian vector gauge field actions generated by charged fermions with particular attention to the thermal regime in odd dimensions, where spectral asymmetry can be present. We show, through z-function regularization, that both small and large gauge invariances are preserved at any temperature and for any number of fermions at the us...
متن کاملOne Loop Superstring Effective Actions and N = 8 Supergravity
In a previous article we have shown the existence of a new independent R4 term, at one loop, in the type IIA and heterotic effective actions, after reduction to four dimensions, besides the usual square of the Bel-Robinson tensor. It had been shown that such a term could not be directly supersymmetrized, but we showed that was possible after coupling to a scalar chiral multiplet. In this articl...
