Logarithmically enhanced Euler-Heisenberg Lagrangian contribution to the electron gyromagnetic factor

The Two-Loop Euler-Heisenberg Lagrangian in Dimensional Renormalization

We clarify a discrepancy between two previous calculations of the two-loop QED Euler-Heisenberg Lagrangian, both performed in proper-time regularization, by calculating this quantity in dimensional regularization. e-mail address D.FliegnerThPhys.Uni-Heidelberg.De e-mail address M.G.SchmidtThPhys.Uni-Heidelberg.De e-mail address [email protected] Supported by Deutsche Forschungsg...

un 2 00 3 IFIC / 02 - 05 The Euler - Kockel - Heisenberg Lagrangian at Finite Temperature

In the present work we investigate temperature effects on the spinor and scalar effective QED, in the context of Thermo Field Dynamics. Following Weisskopf's zero-point energy method, the problem of charge renormalization is reexamined and high temperature contributions are extracted from the thermal correction for the Lagrangian densities.

The 2d Euler-boussinesq Equations with a Logarithmically Supercritical Velocity

This paper establishes the global existence and uniqueness of solutions to a generalized 2D Euler-Boussinesq systems of equations with a logarithmically supercritical velocity.

Logarithmically Improved Criteria for Euler and Navier-Stokes Equations

In this paper we prove the logarithmically improved Beale-Kato-Majda's criterion to the three-dimensional incompressible Euler and Navier-Stokes equations as well as the logarithmically improved Serrin's criteria to the three-dimensional incompressible Navier-Stokes equations.
