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.

Relativistic spin operator and Lorentz transformation of the spin state of a massive Dirac particle [PDF]

open access: yes, 2012
We have shown that the covariant relativistic spin operator is equivalent to the spin operator commuting with the free Dirac Hamiltonian. This implies that the covariant relativistic spin operator is a good quantum observable.

Closed Isometric Linear Transformations of Complex Spacetime endowed with Euclidean, or Lorentz, or generally Isotropic Metric

open access: yesRatio Mathematica, 2022
This paper is the first in a series of papers showing that Newtonian physics and Einsteinian relativity theory can be unified, by using a Generalized Real Boost (GRB), which expresses both the Galilean Transformation (GT) and the Lorentz Boost.

A Completely Invariant SUSY Transform of Supersymmetric QED

open access: yes, 2003
We study the SUSY breaking of the covariant gauge-fixing term in SUSY QED and observe that this corresponds to a breaking of the Lorentz gauge condition by SUSY.

DERIVATION OF THE LORENTZ-EINSTEIN TRANSFORMATION VIA ONE OBSERVER

open access: yesJournal of Engineering, 2010
Lorentz-Einstein transformation derived by Einstein in his theory of special relativity. Physical laws and principles are invariant in all Galilean reference frames under this transformation.

Seiberg-Witten map for noncommutative super Yang-Mills theory

open access: yes, 2002
In this letter we derive the Seiberg-Witten map for noncommutative super Yang-Mills theory in Wess-Zumino gauge. Following (and using results of) hep-th/0108045 we split the observer Lorentz transformations into a covariant particle Lorentz ...

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 ...

Quantum Entanglement of Moving Bodies

open access: yes, 2002
We study the properties of quantum information and quantum entanglement in moving frames. We show that the entanglement between the spins and the momenta of two particles can be interchanged under a Lorentz transformation, so that a pair of particles ...

Covariant Response Theory and the Boost Transform of the Dielectric Tensor

open access: yes, 2017
After a short critique of the Minkowski formulae for the electromagnetic constitutive laws in moving media, we argue that in actual fact the problem of Lorentz-covariant electromagnetic response theory is automatically solved within the framework of ...
