Lorentz Transformation, Poincaré Vectors and Poincaré Sphere in Various Branches of Physics

open access: yesSymmetry, 2018
In the frame of a generic language extended from the polarization theory—comprising the notions of Poincare vectors, Poincare sphere, and P-spheres—a geometric approach to Lorentz transformations alternative to the Minkowskian one is given.

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.

Lorentz Transformation from Symmetry of Reference Principle [PDF]

open access: yes, 2006
The Lorentz Transformation is traditionally derived requiring the Principle of Relativity and light-speed universality. While the latter can be relaxed, the Principle of Relativity is seen as core to the transformation.

Geometrical Interpretation of Space Contraction in Two-dimensional Lorentz Transformation

open access: yesBibechana
This paper points out that the transformation equations for the spatial and temporal coordinates between two frames of reference in the existing generally accepted version of the Lorentz transformation are deficient, since transformation equations are ...

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 ...

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.

Space-Time Symmetries of Noncommutative Spaces [PDF]

open access: yes, 2004
We define a noncommutative Lorentz symmetry for canonical noncommutative spaces. The noncommutative vector fields and the derivatives transform under a deformed Lorentz transformation.

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.
