Cornering the axion-like particle explanation of quasar polarisations

In a series of paper, it has been shown that the distribution of polarisation position angles for visible light from quasars is not random in extremely large regions of the sky. As explained in a recent article, the measurement of vanishing circular polarisation for such quasars is an important problem for a mechanism involving the mixing with axionlike particles in external magnetic fields. In...

The Need for Purely Laboratory-Based Axion-Like Particle Searches

Abstract The PVLAS signal has led to the proposal of many experiments searching for light bosons coupled to photons. The coupling strength probed by these near future searches is, however, far from the allowed region, if astrophysical bounds apply. But the environmental conditions for the production of axion-like particles in stars are very different from those present in laboratories. We consi...

Manifestly N=3 Supersymmetric Euler- Heisenberg Action in Light-Cone Superspace

We find a manifestly N=3 supersymmetric generalization of the four-dimensional Euler-Heisenberg (four-derivative, or F ) part of the Born-Infeld action in light-cone gauge, by using N=3 light-cone superspace. Also at NBI, Univ. of Copenhagen, Denmark, and HCEI, Academy of Sciences, Tomsk, Russia

Two - loop Yang - Mills theory in the world - line formalism and an Euler - Heisenberg type action

Within the framework of the world-line formalism we write down in detail a two-loop EulerHeisenberg type action for gluon loops in Yang-Mills theory and discuss its divergence structure. We exactly perform all the world-line moduli integrals at two loops by inserting a mass parameter, and then extract divergent coefficients to be renormalized. PACS: 11.15.Bt; 11.55.-m; 11.90.+t

Frustrated honeycomb Heisenberg antiferromagnet: A Schwinger-boson approach.

We analyze the frustrated Heisenberg antiferromagnet defined on a honeycomb lattice using a Schwinger-boson mean-field theory. The spin-wave velocity and the susceptibility are presented as functions of the strength of the frustrating interaction for spin S = 12 , and the dynamic structure factor is calculated for various temperatures and frustrations. For large S, we find an increased Néel sta...
