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 ...

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 ...

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.

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.

Lorentz Transformation from Symmetry of Reference Principle [PDF]

, 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 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

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.

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.

Seiberg-Witten map for noncommutative super Yang-Mills theory

, 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 ...
