Comment on ‘Quantum principle of relativity’
New 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
Revista 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.

Science & 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.

Clocks without “Time” in Entangled-State Experiments
Entropy, 2020 Entangled states of light exhibit measurable correlations between light detections at separated locations. These correlations are exploited in entangled-state quantum key distribution.

SciPost Physics Proceedings, 2023 We define new velocity and acceleration having dimension of $(Length)^{\alpha}/(Time)$ and $(Length)^{\alpha}/(Time)^2,$ respectively, based on the fractional addition rule.

A New Perspective on Doubly Special Relativity
Universe, 2023 Doubly special relativity considers a deformation of the special relativistic kinematics parametrized by a high-energy scale, in such a way that it preserves a relativity principle.

Nonlocal special relativity [PDF]
Annalen der Physik, 2008 AbstractIn the special theory of relativity, Lorentz invariance is extended in Minkowski spacetime from ideal inertial observers to actual observers by means of the hypothesis of locality, which postulates that accelerated observers are always pointwise inertial.

Theory of Gravity Dependent on Entropy
Reports in Advances of Physical Sciences, 2023 Gravitational redshift decreases the resolution of measurements, causing entropy by increasing the possible microstates of position and momentum for objects within a gravitational field.

Very Special Relativity as a background field theory [PDF]
, 2016 We consider violation of Lorentz invariance in QED induced by a very high frequency background wave. An effective theory is obtained by averaging observables over the rapid field oscillations.

Beyond special relativity at second order [PDF]
, 2016 The study of generic, nonlinear, deformations of special relativity parametrized by a high-energy scale $M$, which was carried out at first order in $1/M$ in J. M. Carmona, J. L. Cort\'es, and F. Mercati, Phys. Rev.
