How to Violate Lorentz Invariance [PDF]
This article consistes from two parts: the first part is concerned with the subject given in the title and the second part is a tribute to Albert Einstein in the occasion of WYP2005 celebrating his Miracle year, which is given in the Appendix. There are two ways to violate the Lorentz Symmetry of our 4-dimensional space-time; one is to violate the ...

Casimir effect and Lorentz invariance violation [PDF]
The Casimir effect is one of the most direct manifestations of the existence of the vacuum quantum fluctuations, discovered by H. B Casimir in 1948. On the other hand, Lorentz invariance is one of the main and basic concepts in special relativity, which states that, the laws of physics are invariant under Lorentz transformation.

Charged Lifshitz black hole and probed Lorentz-violation fermions from holography
We analytically obtain a new charged Lifshitz solution by adding a non-relativistic Maxwell field in Hořava–Lifshitz gravity. The black hole exhibits an anisotropic scaling between space and time (Lifshitz scaling) in the UV limit, while in the IR limit,

Lorentz and CPT breaking in gamma-ray burst neutrinos from string theory
Previous studies on high-energy gamma-ray burst neutrinos from IceCube suggest a neutrino speed variation at the Lorentz violation (LV) scale of ~6.4 × 1017 GeV, with opposite velocity variances between neutrinos and antineutrinos.

Constraints on Lorentz Invariance Violation with Multiwavelength Polarized Astrophysical Sources
Possible violations of Lorentz invariance (LIV) can produce vacuum birefringence, which results in a frequency-dependent rotation of the polarization plane of linearly polarized light from distant sources.

BARE AND INDUCED LORENTZ AND CPT INVARIANCE VIOLATIONS IN QED [PDF]
We consider QED in a constant axial vector background (Æther). Further Lorentz invariance violations (LIV) might occur owing to radiative corrections. The phenomenology of this model is studied, clarifying issues related to the various regularizations employed, with a particular emphasis on the induced photon mass. To this concern, it is shown that in

A non-perturbative approach to the scalar Casimir effect with Lorentz symmetry violation
We determine the effect of Lorentz invariance violation in the vacuum energy and stress between two parallel plates separated by a distance L, in the presence of a massive real scalar field.

Optical cavity tests of Lorentz invariance for the electron
A hypothetical violation of Lorentz invariance in the electrons' equation of motion (expressed within the Lorentz-violating extension of the standard model) leads to a change of the geometry of crystals and thus shifts the resonance frequency of an ...
