In [M. Zych et al., Nat. Commun. 2, 505 (2011)], the authors predicted that interferometric visibility is affected by a gravitational field in way cannot be explained without general relativistic notion of proper time. this work, we take different route and start deriving same effect using unitary representation local Lorentz transformation Newtonian Limit. addition, show on due to gravity pers...

If Lorentz violation exists, it will affect the thresholds for pair creation processes. Lorentz-violating operators that change the maximum velocities of charged particles may increase or decrease the extinction rate of γ-rays moving through space. If the emissions from high-energy astrophysical sources do not show any signs of anomalous absorption, this allows us to place bounds on the Lorentz...

It is demonstrated how the right hand sides of the Lorentz Transformation equations may be written, in a Lorentz invariant manner, as 4–vector scalar products. This implies the existence of invariant length intervals analagous to invariant proper time intervals. This formalism, making essential use of the 4-vector electromagnetic potential concept, provides a short derivation of the Lorentz for...

In [Gottlieb (1998)] and [Gottlieb (2000)] we launched a study of Lorentz transformations. We find that every Lorentz transformation can be expressed as an exponential e where F is a skew symmetric operator with respect to the Minkowski metric 〈 , 〉 of form −+++. We provided F with the notation of electromagnetism. Thus we can describe boosts as pure ~ E fields and rotations as pure ~ B fields....

We define a noncommutative Lorentz symmetry for canonical noncommutative spaces. Although the Lie algebra of the Poincaré group is undeformed, the noncommutative vector fields and the derivatives transform under a deformed Lorentz transformation. We apply our idea to the case of actions obtained by expanding the star product and the fields taken in the enveloping of the Lie algebra via the Seib...
