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.

Massless Dirac Fermions on a Space‐Time Lattice with a Topologically Protected Dirac Cone

open access: yesAnnalen der Physik, Volume 534, Issue 12, December 2022., 2022
Fermion doubling is a lattice artefact that appears if one discretizes the Dirac equation of massless electrons. One can work around this obstacle by replacing the linear dispersion by a sawtooth. Here it is shown that this method opens a gap at the Dirac point of the band structure.

Local Lorentz transformations and Thomas effect in general relativity [PDF]

open access: yesPhys. Rev. D 93, 124050 (2016), 2016
The tetrad method is used for an introduction of local Lorentz frames and a detailed analysis of local Lorentz transformations. A formulation of equations of motion in local Lorentz frames is based on the Pomeransky-Khriplovich gravitoelectromagnetic fields.

The Lorentz Transformation [PDF]

open access: yesNature, 1946
IN a letter entitled “A Simple Proof of the Lorentz Transformation” appearing in Nature1, an error has been introduced into the matrix algebra, the correction of which requires a certain recasting of the proof.

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 ...

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 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.

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.

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.

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.
