Derivations of relativistic force transformation equations [PDF]

open access: yes, 2011
The correct general form of relativistic transformation equations for the three-vector force is derived without using four-vectors, via the relativistic Newton's second law. The four-vector approach to the problem is also presented.

Implications of an absolute simultaneity theory for cosmology and universe acceleration. [PDF]

open access: yesPLoS ONE, 2014
An alternate Lorentz transformation, Absolute Lorentz Transformation (ALT), has similar kinematics to special relativity yet maintains absolute simultaneity in the context of a preferred reference frame.

Black hole entropy in the Chern–Simons-like theories of gravity and Lorentz-diffeomorphism Noether charge

open access: yesNuclear Physics B, 2016
In the first order formalism of gravity theories, there are some theories which are not Lorentz-diffeomorphism covariant. In the framework of such theories we cannot apply the method of conserved charge calculation used in Lorentz-diffeomorphism ...

Lorentz quantum mechanics

open access: yesNew Journal of Physics, 2018
We present a theoretical framework for the dynamics of bosonic Bogoliubov quasiparticles. We call it Lorentz quantum mechanics because the dynamics is a continuous complex Lorentz transformation in complex Minkowski space.

Potential relativistic dispersion in material medium

open access: yesResults in Physics, 2016
Lorentz space-time transformation has been applied to the phase factor of a plane electromagnetic wave in linear material medium. The derivation shows in the limiting case for v = c, the phase velocity converges to its monochromatic value implying no ...

Lorentz transformation by mimicking the Lorentz transformation

open access: yes, 2007
We show that starting with the fact that special relativity theory is concerned with a distortion of the observed length of a moving rod, without mentioning if it is a "contraction" or "dilation", we can derive the Lorentz transformations for the spacetime coordinates of the same event.

Discrete Lorentz covariance for quantum walks and quantum cellular automata

open access: yesNew Journal of Physics, 2014
We formalize a notion of discrete Lorentz transforms for quantum walks (QW) and quantum cellular automata (QCA), in $(1+1)$ -dimensional discrete spacetime.

4-component spinors for SL(4,C), their transformation properties and two types of Lorentz transformations [PDF]

open access: yes, 2023
We define a spinor-Minkowski metric for SL(4,C). It is not a trivial generalization of the SL(2,C) metric and it involves the Minkowski metric. We define 4x4 version of the Pauli matrices and their 4-component generalized eigenvectors. These eigenvectors

Supertranslation-invariant dressed Lorentz charges

open access: yesJournal of High Energy Physics, 2022
We present an explicit formula for Lorentz boosts and rotations that commute with BMS supertranslations in asymptotically flat spacetimes. Key to the construction is the use of infrared regularizations and of a unitary transformation that makes ...

Formulation of the Lorentz transformation equations in the three dimensions of space

open access: yesSt. Petersburg Polytechnical University Journal: Physics and Mathematics
The Lorentz transformation of space and time between two inertial frames of reference is one of the pillars of the special theory of relativity. Until now, the Lorentz transformation equations have been considered on the base of one-dimensional motion ...
