Special relativity on the light-front

open access: yesRevista Brasileira de Ensino de Física, 2021
P.A.M. Dirac in 1949 showed that it is possible to construct relativistic dynamic forms starting from the description of the initial state of a given relativistic system in any space-time surface whose distances between two points on this hypersurface ...

An Improved Framework for Quantum Gravity

open access: yesUniverse, 2020
General relativity has two fundamental problems that render it unsuitable for tackling the gravitational field’s quantization. The first problem is the lack of a genuine gravitational variable representing gravitation only, inertial forces apart.

Comment on ‘Quantum principle of relativity’

open access: yesNew Journal of Physics, 2023
Dragan and Ekert in the paper (2020 New. J. Phys. 22 033038) presented ‘quantum principle of relativity’ (QPR) based on Galilean principle of relativity, which involves both superluminal G _S and subluminal G _s families of observers and argue that then ...

An alternative way to present a relativistic Lagrangian definition

open access: yesRevista Brasileira de Ensino de Física, 2021
As long we known, the non-relativistic Lagrangian definition, L = T − U with T and U as being, respectively, kinetic and potential energy, it is not valid at the relativistic level.

Generalizations of Snyder model to curved spaces

open access: yesPhysics Letters B, 2022
We consider generalizations of the Snyder algebra to a curved spacetime background with de Sitter symmetry. As special cases, we obtain the algebras of the Yang model and of triply special relativity.

Symmetry and Special Relativity [PDF]

open access: yesSymmetry, 2019
We explore the role of symmetry in the theory of Special Relativity. Using the symmetry of the principle of relativity and eliminating the Galilean transformations, we obtain a universally preserved speed and an invariant metric, without assuming the constancy of the speed of light.

Correcting the Doppler Effect

open access: yesScience & Philosophy, 2023
Christian Doppler, an Austrian physicist, described in 1842 the apparent change in frequency of a wave when motion of the source or the observer is involved. Named after him, this change in observational frequencies is known as the Doppler Effect.
