Reduction of the Finsler gravity vacuum equation and dynamics for the cosmological Landsberg spacetimes
Christian Pfeifer, Fidel F. Villaseñor
When solving the Einstein vacuum equations, a very helpful feature is that they reduce simply to the vanishing of the Ricci tensor. In Finsler gravity, a promising extension of gen…
On spherically symmetric Berwald vacuum solutions in Finsler gravity
Nicoleta Voicu, Diana - Maria Birla, Christian Pfeifer
Berwald-Finsler spacetimes are Finsler spacetimes that are closest to pseudo-Riemannian geometry, as their canonical nonlinear connection defines an affine connection on spacetime.…
Light deflection in axially symmetric stationary spacetimes filled with a moving medium
Christian Pfeifer, Barbora Bezděková, Oleg Yu. Tsupko
The deflection of light rays near gravitating objects can be influenced not only by gravity itself but also by the surrounding medium. Analytical studies of such effects are possib…
From kinetic gases to an exponentially expanding universe - The Finsler-Friedmann equation
Christian Pfeifer, Nicoleta Voicu, Annamaria Friedl-Szász +1
We investigate the gravitational field of a kinetic gas beyond its usual derivation from the second moment of the one-particle distribution function (1PDF), that serves as energy-m…
Experimental Bounds on Deformed Muon Lifetime Dilation
Iarley P. Lobo, Christian Pfeifer, Pedro H. Morais
We analyze Planck scale induced modifications of the relativistic time dilation using data from the Muon Storage Ring experiment at CERN. By examining the lifetimes of muons, we es…
Weak equivalence principle and nonrelativistic limit of general dispersion relations
Manuel Hohmann, Christian Pfeifer, Fabian Wagner
We study the weak equivalence principle in the context of modified dispersion relations, a prevalent approach to quantum gravity phenomenology. We find that generic modified disper…
Deflection of light rays in a moving medium around a spherically symmetric gravitating object
Barbora Bezděková, Oleg Yu. Tsupko, Christian Pfeifer
In most analytical studies of light ray propagation in curved spacetimes around a gravitating object surrounded by a medium, it is assumed that the medium is a cold nonmagnetized p…
