Worldline Approach To The Casimir Effect
L. Moyaerts, K. Langfeld, H. Gies
We present a new method to compute quantum energies in presence of a background field. The method is based on the string-inspired worldline approach to quantum field theory and its…
Renormalization flow from UV to IR degrees of freedom
Holger Gies, Christof Wetterich
Within the framework of exact renormalization group flow equations, a scale-dependent transformation of the field variables provides for a continuous translation of UV to IR degree…
Applications of the Light Cone Condition for various perturbed Vacua
Walter Dittrich, Holger Gies
We examine the propagation of light in the presence of various modifications of the QED vacuum in the limit of low frequency. A polarization summed and direction averaged-light con…

Walter Dittrich, Holger Gies
Table of Contents 1. One-loop effective Lagrangian in spinor QED. 2. Dispersion effects for low-frequency photons. 3. Vacuum birefringence in magnetic fields. 4. Light cone conditi…
