European Physical Journal C: Particles and Fields, 2023 The phenomena of neutrino oscillations offer a great potential for probing new-physics beyond the Standard Model. Any additional effects on neutrino oscillations can help understand the nature of the non-standard effects.

Lorentz and CPT Violation in Scalar-Mediated Potentials [PDF]
, 2013 In Lorentz- and CPT-violating effective field theories involving scalar and spinor fields, there exist forms of Lorentz violation that modify only the scalar-spinor Yukawa interaction vertices.

Chorus Wave–Driven Electron Dynamics in the Van Allen Belts: From Coherence to Diffusion
AGU Advances, Volume 6, Issue 6, December 2025.Abstract The Van Allen radiation belts contain relativistic electrons trapped by Earth's magnetic field, posing serious risks to spacecraft. Chorus waves are known to accelerate these electrons via resonant interactions, but these interactions are inherently nonlinear and coherent.

Lorentz violation and ultrahigh-energy photons [PDF]
Physical Review D, 2008 The propagation of photons, electrons and positrons at ultra-high energies above 10^{19} eV can be changed considerably if the dispersion relations of these particles are modified by terms suppressed by powers of the Planck scale. We recently pointed out that the current non-observation of photons in the ultra-high energy cosmic ray flux at such ...

Physics Letters B, 2016 We study the perturbative generation of higher-derivative Lorentz violating operators as quantum corrections to the photon effective action, originated from a specific Lorentz violation background, which has already been studied in connection with the ...

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.

Phenomenologically Viable Lorentz-Violating Quantum Gravity [PDF]
Physical Review Letters, 2009 Horava's "Lifschitz point gravity" has many desirable features, but in its original incarnation one is forced to accept a non-zero cosmological constant of the wrong sign to be compatible with observation. We develop an extension of Horava's model that abandons "detailed balance", and in 3+1 dimensions exhibit all five marginal (renormalizable) and ...

Lorentz invariance and quantum gravity: an additional fine-tuning problem? [PDF]
, 2004 Trying to combine standard quantum field theories with gravity leads to a breakdown of the usual structure of space-time at around the Planck length, 1.6*10^{-35} m, with possible violations of Lorentz invariance.
