Fermionic Casimir energy in Horava–Lifshitz scenario

European Physical Journal C: Particles and Fields
In this work, we investigate the violation of Lorentz symmetry through the Casimir effect, one of the most intriguing phenomena in modern physics. The Casimir effect, which represents a macroscopic quantum force between two neutral conducting surfaces ...

Electrically charged black holes in gravity with a background Kalb–Ramond field

European Physical Journal C: Particles and Fields
We derive the exact solutions for electrically charged black holes both in the absence and presence of a cosmological constant in the gravitational theory with Lorentz violation induced by a background Kalb–Ramond (KR) field.

Lorentz Invariance Violation from Gamma-Ray Bursts

The Astrophysical Journal
Lorentz invariance violation (LV) is examined through the time delay between high-energy and low-energy photons in gamma-ray bursts (GRBs). Previous studies determined the LV energy scale as E _LV ≃ 3.60 × 10 ^17 GeV using Fermi Gamma-ray Space Telescope

Flavor-changing Lorentz and CPT violation in muonic atoms

Physics Letters B
Flavor-changing signatures of Lorentz and CPT violation involving muon-electron conversions in muonic atoms are studied using effective field theory.

Vacuum Cherenkov radiation for nonminimal dimension-5 Lorentz violation

European Physical Journal C: Particles and Fields
Vacuum Cherenkov radiation is investigated in the Lorentz-violating Standard-Model Extension for isotropic dim-5 operators $$\hat{m}$$ m ^ and $$\hat{a}^{\mu }$$ a ^ μ in the fermion sector. Both the kinematics and dynamics of this process are studied by
