A novel approach to light-front perturbation theory
T. Heinzl
We suggest a possible algorithm to calculate one-loop n-point functions within a variant of light-front perturbation theory. The key ingredients are the covariant Passarino-Veltman…
Color Screening, Casimir Scaling, and Domain Structure in G(2) and SU(N) Gauge Theories
J. Greensite, K. Langfeld, S. Olejnik +2
We argue that screening of higher-representation color charges by gluons implies a domain structure in the vacuum state of non-abelian gauge theories, with the color magnetic flux…
Initial States: IR and Collinear Divergences
Martin Lavelle, David McMullan
The standard approach to the infra-red problem is to use the Bloch-Nordsieck trick to handle soft divergences and the Lee-Nauenberg (LN) theorem for collinear singularities. We sho…
Magnetoresistance in Thin Permalloy Film (10nm-thick and 30-200nm-wide) Nanocontacts Fabricated by e-Beam Lithography
Nicolas Garcia, Cheng Hao, Lu Yonghua +7
In this paper we show spin dependent transport experiments in nanoconstrictions ranging from 30 to 200nm. These nanoconstrictions were fabricated combining electron beam lithograph…
Phase Structure of Z(3)-Polyakov-Loop Models
Christian Wozar, Tobias Kaestner, Andreas Wipf +2
We study effective lattice actions describing the Polyakov loop dynamics originating from finite-temperature Yang-Mills theory. Starting with a strong-coupling expansion the effect…
Large orders in strong-field QED
Thomas Heinzl, Oliver Schroeder
We address the issue of large-order expansions in strong-field QED. Our approach is based on the one-loop effective action encoded in the associated photon polarisation tensor. We…
Ferromagnetic Wires Composite Media with Tunable Scattering Spectra at Microwaves
D. P. Makhnovskiy, L. V. Panina, C. Garcia +2
We demonstrate composite media with ferromagnetic wires that exhibit a frequency region at the microwave regime with scattering spectra strongly dependent on an external magnetic f…
Quantum stabilization of Z-strings in the electroweak model
Oliver Schroeder
We study the quantum energy of the Z-string in 2+1 dimensions using the phase shift formalism. Our main interest is the question of stability of a Z-string carrying a finite fermio…
On the Observation of Vacuum Birefringence
T. Heinzl, B. Liesfeld, K. -U. Amthor +3
We suggest an experiment to observe vacuum birefringence induced by intense laser fields. A high-intensity laser pulse is focused to ultra-relativistic intensity and polarizes the…
