Lorentz quantum mechanics

New 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

Results 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 ...

Reply to ``A Simple Derivation of the Lorentz Transformation''

, 2017
The theory of Relativity is consistent with the Lorentz transformation. Thus Pr. Levy proposed a simple derivation of it, based on the Relativity postulates. A reply is provided: Some related results (five ones) are found and developed step by step which

Supertranslation-invariant dressed Lorentz charges

Journal 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 ...

Discrete Lorentz covariance for quantum walks and quantum cellular automata

New 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.

The Equations of Lorentz Transformation

, 2016
This work consists of two parts. The first part: The Lorentz transformation has two derivations. One of the derivations can be found in the references at the end of the work in the “Appendix I” of the book marked by number one.

A Completely Invariant SUSY Transform of Supersymmetric QED

, 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.

Geometrical approach to the proton spin decomposition [PDF]

, 2013
We discuss in detail and from the geometrical point of view the issues of gauge invariance and Lorentz covariance raised by the approach proposed recently by Chen et al. to the proton spin decomposition. We show that the gauge invariance of this approach

Lorentz transformation by mimicking the Lorentz transformation

, 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.

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

Ratio 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.
