Physical interpretation of large Lorentz violation via Weyl semimetals
New Journal of PhysicsThe physical intepretation of effective field theories of fundamental interactions incorporating large Lorentz violation is a long-standing challenge, known as the concordance problem.

Massless and Massive Vector Goldstone Bosons in Nonlinear Quantum Electrodynamics [PDF]
, 2006 The spontaneous Lorentz invariance violation (SLIV) developing in QED type theories with the nonlinear four-vector field constraint $A_{\mu}^{2}=M^{2}$ (where $M$ is a proposed scale of the Lorentz violation) is considered in the case when the internal U(

Lorentz Violation in Extra Dimensions
, 2005 In theories with extra dimensions it is well known that the Lorentz invariance of the $D=4+n$-dimensional spacetime is lost due to the compactified nature of the $n$ dimensions leaving invariance only in 4d.

The simplicity of physical laws
Noûs, Volume 59, Issue 4, Page 957-987, December 2025.Abstract Physical laws are strikingly simple, yet there is no a priori reason for them to be so. I propose that nomic realists—Humeans and non‐Humeans—should recognize simplicity as a fundamental epistemic guide for discovering and evaluating candidate physical laws.

European Physical Journal C: Particles and Fields, 2020 This paper investigates the impact of hypothetical Lorentz invariance violation on the $$t\bar{t}$$ tt¯ production at the LHC and future hadron colliders. Possible deviations from Lorentz symmetry remain poorly constrained in the top quark sector. With a

Performance Comparison Between Bifacial PERC and TOPCon on a South‐Facing Vertical Structure
Energy Science &Engineering, Volume 13, Issue 11, Page 5566-5573, November 2025.We fabricated modules using Tunnel Oxide Passivated Contact and Passivated Emitter and Rear Contact solar cells, installed them outdoors, and compared their energy yields. This paper examines the factors contributing to the differences in energy yield, considering everything from the manufacturing processes of each solar cell to their electrical ...

Ring Current Ion Scattering by Electromagnetic Ion Cyclotron Waves: Nonlinear Resonance Effects
Journal of Geophysical Research: Space Physics, Volume 130, Issue 11, November 2025.Abstract Electromagnetic ion cyclotron (EMIC) waves can interact with ring current ions and scatter them into the atmosphere. The classical framework for studying EMIC wave–ion interaction is the quasi‐linear theory, which relies on the approximation of weak perturbations of particle trajectories for a single resonant interaction. However, intense EMIC
