Mapping Lorentz invariance violations into equivalence principle violations [PDF]
Physics Letters B, 1999 We point out that equivalence principle violations, while not dynamically equivalent, produce the same kinematical effects as Lorentz invariance violations for particle processes in a constant gravitational potential. This allows us to translate many experimental bounds on Lorentz invariance violations into bounds on equivalence principle violations ...

Supershift properties for nonanalytic signals
Nanophotonics, Volume 14, Issue 23, Page 4039-4044, 02 November 2025.Abstract The phenomenon of superoscillations is of great interest in microscopy, antenna design, and material sciences. This phenomenon has been generalized and has given rise to the concept of supershift, which is a far reaching extension that applies to functions that may present discontinuous derivatives. From this perspective, this is a notion that

Inhomogeneous broadening in the time domain
Nanophotonics, Volume 14, Issue 23, Page 4177-4196, 02 November 2025.Abstract Forty‐five years after the initial attempts – first by Efimov–Khitrov in 1979, then by Brendel–Bormann in 1992 – we present a comprehensive, causal, and physically consistent framework for modeling the dielectric function with inhomogeneous (non‐Lorentzian) broadening, where scattering becomes frequency‐ or time‐dependent.

SUPERFIELD REALIZATIONS OF LORENTZ VIOLATION [PDF]
Quantum Theory and Symmetries, 2004 Lorentz-violating extensions of the Wess-Zumino model have been formulated in superspace. The models respect a supersymmetry algebra and can be understood as arising from suitably modified superspace transformations.

Supersymmetry with Lorentz symmetry violation
Physical Review D, 2023 We study two (massless free field) models, a photon/photino model with a vector gauge field and a Majorana spinor field, and a Wess-Zumino model. They each exhibit Lorentz symmetry violation but retain, in an appropriate way, the supersymmetry correspondance between the particles of the two fields.

Aggregate, Volume 6, Issue 11, November 2025.This review clarifies the multiscale coupling mechanisms between macroscopic mechanics (e.g., surface tension, fluid shear, interfacial stress) and atomic assembly, highlighting the importance of mechanical regulation in suppressing solute aggregation and guiding crystal orientation.

LORENTZ VIOLATION BY QUARK CONDENSATION [PDF]
CPT and Lorentz Symmetry, 2010 At the TeV scale, heavy quarks, for example the 4th generation quarks of the Standard Model with four generations, can form condensates which dynamically break the electroweak symmetry. A dense quark system may form other types of condensates which dynamically break the Lorentz symmetry.

Sensitivity to CP discovery in the presence of Lorentz invariance-violating potential at T2HK/T2HKK
European Physical Journal C: Particles and FieldsThe investigation of conservation/violation of conjugation and parity (CP) symmetry in the leptonic sector is essential to understanding the evolution of the universe. Lorentz invariance and CPT are fundamental symmetries of nature.

Neutrino Oscillations and Lorentz Invariance Violation
Universe, 2020 This work explores the possibility of resorting to neutrino phenomenology to detect evidence of new physics, caused by the residual signals of the supposed quantum structure of spacetime.
