Photon production from the scattering of axions out of a solenoidal magnetic field
We calculate the total cross section for the production of photons from the scattering of axions by a strong inhomogeneous magnetic field in the form of a 2D δ-function, a cylindrical step function…
Coupling Electromagnetism to Global Charge
It is shown that an alternative to the standard scalar quantum electrodynamics (QED) is possible. In this new version, there is only global gauge invariance as far as the charged scalar fields are…
Radio-loud Magnetars as Detectors for Axions and Axion-like Particles
We show that, by studying the arrival times of radio pulses from highly-magnetized transient beamed sources, it may be possible to detect light pseudo-scalar particles, such as axions and axion-like…
Cosmic Analogs of the Stern-Gerlach Experiment and the Detection of Light Bosons
We show that, by studying the arrival times of radio pulses from highly magnetized pulsars, it may be possible to detect light spin-0 bosons (such as axions and axion-like particles) with a much…
AXIONS SCATTERING FROM A QUADRUPOLE MAGNETIC FIELD
We study the 2D scattering of axions from an accelerator like quadrupole magnet using the eikonal approximation in order to learn whether or not such a setup could serve as a new possible method for…

Continuous axion photon duality and its consequences
The axion–photon system in an external magnetic field, when for example considered with the geometry of the experiments exploring axion–photon mixing, displays a continuous axion–photon duality…
Mass generation and instabilities in the presence of external fields and axions
Small fluctuations around a constant electric or constant magnetic field F are analyzed in a theory with pseudo scalar [phi] with a coupling g[phi]F~F. It is found that a magnetic external field…
Confinement effects from interacting chromo-magnetic and axion fields
We study a non-Abelian gauge theory with a pseudo scalar coupling Tr(F*μνFμν) in the case where a constant chromo-electric, or chromo-magnetic, strength expectation value is present. We compute the…
CONFINEMENT IN THE PRESENCE OF EXTERNAL FIELDS AND AXIONS
For a theory with a pseudo-scalar coupling and in the case that there is a constant electric or magnetic strength expectation value, we compute the interaction potential within the structure of the…
Symmetry breaking induced by charge density and the entropy of interacting fields.
- PhysicsPhysical review. D, Particles and fields
It appears that higher-dimensional solitons are still forbidden in the presence of finite charge density, and it is shown that degenerate ground states appear when the system is considered as a charged medium, which the authors take to be so large that it makes sense to speak of a uniform, finite, charge density.
Photon regeneration from pseudoscalars at X-ray laser facilities.
- PhysicsPhysical review letters
This work proposes a method of independently testing an anomalously large rotation of the polarization of light in the presence of a magnetic field in vacuum using a high-energy photon regeneration experiment using the synchrotron x rays from a free-electron laser.

A new light boson
It is pointed out that a global U(1) symmetry, that has been introduced in order to preserve the parity and time-reversal invariance of strong interactions despite the effects of instantons, would…
Proposed experiment to produce and detect light pseudoscalars.
- PhysicsPhysical review letters
A laboratory experiment to produce and detect a light neutral pseudoscalar particle that couples to two photons that compete favorably with astrophysical limits and would substantially improve those from direct measurements.
