Finsler spacetime geometry in Physics

C Pfeifer - International Journal of Geometric Methods in Modern …, 2019 - World Scientific
Finsler geometry naturally appears in the description of various physical systems. In this
review, I divide the emergence of Finsler geometry in physics into three categories: dual …

Modified gravity and cosmology

EN Saridakis, R Lazkoz, V Salzano, PV Moniz… - 2021 - Springer
The dawn of the twenty-first century came with very positive prospects for gravity, cosmology,
and astrophysics. Technological progress made it possible for cosmology to enter to its …

Emergent models for gravity: an overview of microscopic models

L Sindoni - SIGMA. Symmetry, Integrability and Geometry: Methods …, 2012 - emis.de
We give a critical overview of various attempts to describe gravity as an emergent
phenomenon, starting from examples of condensed matter physics, to arrive to more …

Finsler gravity action from variational completion

M Hohmann, C Pfeifer, N Voicu - Physical Review D, 2019 - APS
In the attempts to apply Finsler geometry to construct an extension of general relativity, the
question about a suitable generalization of the Einstein equations is still under debate …

Coherent states for generalized uncertainty relations as Tsallis probability amplitudes: New route to nonextensive thermostatistics

P Jizba, G Lambiase, GG Luciano, L Petruzziello - Physical Review D, 2023 - APS
We study coherent states associated with a generalized uncertainty principle (GUP). We
separately analyze the cases of positive and negative deformation parameter β, showing …

Reaching the Planck scale with muon lifetime measurements

IP Lobo, C Pfeifer - Physical Review D, 2021 - APS
Planck scale modified dispersion relations are one way to capture the influence of quantum
gravity on the propagation of fundamental point particles effectively. We derive the time …

Causal structure and electrodynamics on Finsler spacetimes

C Pfeifer, MNR Wohlfarth - Physical Review D—Particles, Fields, Gravitation …, 2011 - APS
We present a concise new definition of Finsler spacetimes that generalizes Lorentzian
metric manifolds and provides consistent backgrounds for physics. Extending standard …

Hamilton geometry: Phase space geometry from modified dispersion relations

L Barcaroli, LK Brunkhorst, G Gubitosi, N Loret… - Physical Review D, 2015 - APS
We describe the Hamilton geometry of the phase space of particles whose motion is
characterized by general dispersion relations. In this framework spacetime and momentum …

Mathematical foundations for field theories on Finsler spacetimes

M Hohmann, C Pfeifer, N Voicu - Journal of Mathematical Physics, 2022 - pubs.aip.org
This paper introduces a general mathematical framework for action-based field theories on
Finsler spacetimes. As most often fields on Finsler spacetime (eg, the Finsler fundamental …

Berwald spacetimes and very special relativity

A Fuster, C Pabst, C Pfeifer - Physical Review D, 2018 - APS
In this work, we study Berwald spacetimes and their vacuum dynamics, where the latter are
based on a Finsler generalization of Einstein's equations derived from an action on the unit …
