dc.description.abstract
In 1936, Weisskopf [K. Dan. Vidensk. Selsk. Mat. Fys. Medd. XIV (1936)] showed
that for vanishing electric or magnetic fields the strong-field behavior of
the one-loop Euler-Heisenberg effective Lagrangian of quantum electro dynamics
(QED) is logarithmic. Here we generalize this result for different limits of
the Lorentz invariants E⃗ 2−B⃗ 2 and B⃗ ·E⃗ . The logarithmic dependence can
be interpreted as a lowest-order manifestation of an anomalous power behavior
of the effective Lagrangian of QED, with critical exponents δ=e2/(12π) for
spinor QED, and δS=δ/4 for scalar QED.
