Vacuum Birefringence in a Rotating Magnetic Field

We calculate the vacuum polarization-induced ellipticity acquired by a linearly polarized laser beam of angular frequency ω̄ on traversing a region containing a transverse magnetic field rotating with a small angular velocity Ω around the beam axis. The transmitted beam contains the fundamental frequency ω̄ and weak sidebands of frequency ω̄±2Ω, but no other sidebands. To first order in small quan...

Active compensation of magnetic field distortions based on vector spherical harmonics field description

Vacuum Geometry

We analyse symmetry breaking in general gauge theories paying particular attention to the underlying geometry of the theory. In this context we find two natural metrics upon the vacuum manifold: a Euclidean metric associated with the scalar sector, and another generally inequivalent metric associated with the gauge sector. Physically, the interplay between these metrics gives rise to many of th...

Vacuum-field-induced filamentation in laser-beam propagation

As a laser beam passes through a material medium, it is often observed to break up into a large number of filaments @1#. This filamentation process is initiated by the presence of weak perturbations on the laser wave front @2,3#, which can grow by means of four-wave-mixing processes @4# and become large enough to disturb the overall propagation of the beam. Laser-beam filamentation can be suppr...
