Gravitational lensing effect in the Universe with a Finsler background

B Shen - Journal of Geometry and Physics, 2023 - Elsevier
The gravitational deflection of light is a common effect for the massive objects in galactic
astronomy. Recently, several universal models with Finsler background were introduced to …

Quasinormal modes of a scalar and an electromagnetic field in Finslerian-Schwarzschild spacetime

X Li, SP Zhao - Physical Review D, 2020 - APS
Quasinormal modes of scalar field and electromagnetic field in a specific Finslerian-
Schwarzschild spacetime have been investigated in this paper. The equations of motion for …

An anisotropic gravity theory

A Garcia-Parrado, E Minguzzi - General Relativity and Gravitation, 2022 - Springer
We study an action integral for Finsler gravity obtained by pulling back an Einstein-Cartan-
like Lagrangian from the tangent bundle to the base manifold. The vacuum equations are …

Electromagnetic and gravitational interactions from Lagrangian mechanics

P Maraner - Annals of Physics, 2021 - Elsevier
Background fields of electromagnetic and gravitational type emerge in the low kinetic energy
limit of any regular Lagrangian system and, in particular, in the corresponding limit of any …
