The language of Einstein spoken by optical instruments [PDF]
, 2004 Einstein had to learn the mathematics of Lorentz transformations in order to complete his covariant formulation of Maxwell's equations. The mathematics of Lorentz transformations, called the Lorentz group, continues playing its important role in optical ...

Lorentz transformations of open systems [PDF]
, 2001 We consider open dynamical systems, subject to external interventions by agents that are not completely described by the theory (classical or quantal). These interventions are localized in regions that are relatively spacelike. Under these circumstances,

Noncommutative spaces and Poincaré symmetry
Physics Letters B, 2017 We present a framework which unifies a large class of noncommutative spacetimes that can be described in terms of a deformed Heisenberg algebra. The commutation relations between spacetime coordinates are up to linear order in the coordinates, with ...

On Non-Abelian Structure From Matrix Coordinates [PDF]
, 2001 We consider the matrix quantum mechanics of N D0-branes in the background of the 1-form RR field. It is observed that the transformations of matrix coordinates of D0-branes induce on the Abelian RR field symmetry transformations that are like those of ...

Deduction of Lorentz Transformations from Classical Thermodynamics
Entropy, 2015 The Lorentz transformations are obtained by assuming that the laws of classical thermodynamics are invariant under changes of inertial reference frames.

Kinematical solution of the UHE-cosmic-ray puzzle without a preferred class of inertial observers [PDF]
, 2002 Among the possible explanations for the puzzling observations of cosmic rays above the GZK cutoff there is growing interest in the ones that represent kinematical solutions, based either on general formulations of particle physics with small violations ...

Gauge and Lorentz Transformation Placed on the Same Foundation
Advances in Mathematical Physics, 2011 We show that a “dynamical” interaction for arbitrary spin can be constructed in a straightforward way if gauge and Lorentz transformations are placed on the same foundation.

Superboost transitions, refraction memory and super-Lorentz charge algebra
Journal of High Energy Physics, 2018 We derive a closed-form expression of the orbit of Minkowski spacetime under arbitrary Diff(S 2) super-Lorentz transformations and supertranslations. Such vacua are labelled by the superboost, superrotation and supertranslation fields.

Noether-Wald charge in supergravity: the fermionic contribution
Journal of High Energy Physics, 2023 We study the invariance of N $$ \mathcal{N} $$ = 1, d = 4 supergravity solutions under diffeormophisms and show that, in order to obtain consistent conditions (“Killing equations”) invariant under local supersymmetry transformations, one has to perform ...

Information under Lorentz Transformation [PDF]
Communications in Theoretical Physics, 2014 A general form of a two-qubit system is obtained under the effect of Lorentz transformation. We investigate extensively some important classes in the context of quantum information. It is shown Lorentz transformation causes a decay of entanglement and consequently information loses.
