Lorentz violation of quantum gravity [PDF]

Classical and Quantum Gravity, 2010
A quantum gravity theory which becomes renormalizable at short distances due to a spontaneous symmetry breaking of Lorentz invariance and diffeomorphism invariance is studied. A breaking of Lorentz invariance with the breaking patterns $SO(3,1)\to O(3)$ and $SO(3,1)\to O(2)$, describing 3+1 and 2+1 quantum gravity, respectively, is proposed.

Physical interpretation of large Lorentz violation via Weyl semimetals

New Journal of Physics
The physical intepretation of effective field theories of fundamental interactions incorporating large Lorentz violation is a long-standing challenge, known as the concordance problem.

Lorentz violation signatures in the low-energy sector of Hořava gravity from black hole shadow observations

Physics Letters B
In this paper, we use the Hořava gravity model and EHT observations of supermassive black holes (BHs) to investigate signatures of Lorentz violation in real astrophysical environments.

QED Tests of Lorentz Symmetry

, 2004
A status report is given of some recent theoretical and experimental investigations looking for signals of Lorentz violation in QED. Experiments with light, charged particles, and atoms have exceptional sensitivity to small shifts in energy caused by ...

Lorentz Violation and Short-Baseline Neutrino Experiments [PDF]

, 2004
A general discussion is given of signals for broken Lorentz symmetry in short-baseline neutrino experiments. Among the effects that Lorentz violation can introduce are a dependence on energy differing from that of the usual massive-neutrino solution and ...

Systematic Study of PDMS Optical Waveguides for Pressure Sensing Using Design of Experiments

Journal of Applied Polymer Science, EarlyView.
A response surface methodology was used to systematically evaluate the impact of mix ratio and cure conditions on PDMS optical waveguide properties for pressure sensing. Mix ratio significantly influenced compression sensitivity, compressive modulus, and propagation loss, while cure temperature primarily affected refractive index.

Trajectories of astroparticles in pseudo-Finsler spacetime with the most general modified dispersion

European Physical Journal C: Particles and Fields, 2023
Finsler geometry is a natural and fundamental generalization of Riemann geometry, and is a tool to research Lorentz invariance violation. We find the connection between the most general modified dispersion relation and a pseudo-Finsler structure, and ...
