Spacetime Variation of Lorentz-Violation Coefficients at Nonrelativistic Scale

TL;DR

This paper investigates how Lorentz-violation coefficients in the Standard-Model Extension vary across spacetime and explores their effects at nonrelativistic scales, linking theoretical variations to experimental sensitivities.

Contribution

It analyzes the consequences of spacetime-dependent Lorentz-violation coefficients in curved spacetime within the SME framework, focusing on nonrelativistic effects and experimental sensitivities.

Findings

Derived sensitivity of experiments to derivatives of SME coefficients

Identified effects of spacetime variation of Lorentz-violation coefficients

Explored implications for nonrelativistic physics

Abstract

When the Standard-Model Extension (SME) is applied in curved spacetime, the Lorentz-violation coefficients must depend on spacetime position. This work describes some of the consequences of this spacetime variation. We focus on effects that appear at a nonrelativistic scale and extract sensitivity of completed experiments to derivatives of SME coefficient fields.
