Abstract
We investigate the propagation characteristics of apertured Gaussian and Bessel beams in a nontrivial spacetime background characterized by a constant 4-vector. Such 4-vector introduces a privileged direction in spacetime, thus breaking Lorentz invariance. The scalar beam is modeled by a massless scalar field theory, which corresponds to the scalar sector of the standard model extension. Assuming an axially symmetric Lorentz-violating background, we employ the Green’s function method to investigate the propagated field for particular input fields. We investigate the impact of the Lorentz-violating parameter upon the intensity and focalization of the beams. Finally, we discuss possible realizations in optically transparent multiferroic materials.
期刊介绍：
The aims of this peer-reviewed online journal are to distribute and archive all relevant material required to document, assess, validate and reconstruct in detail the body of knowledge in the physical and related sciences.
The scope of EPJ Plus encompasses a broad landscape of fields and disciplines in the physical and related sciences - such as covered by the topical EPJ journals and with the explicit addition of geophysics, astrophysics, general relativity and cosmology, mathematical and quantum physics, classical and fluid mechanics, accelerator and medical physics, as well as physics techniques applied to any other topics, including energy, environment and cultural heritage.
