Constraints on Nonmetricity from Bounds on Lorentz Violation

arXiv:1612.08744 · doi:10.1103/PhysRevD.95.084033

Abstract

Spacetime nonmetricity can be studied experimentally through its couplings to fermions and photons. We use recent high-precision searches for Lorentz violation to deduce first constraints involving the 40 independent nonmetricity components down to levels of order $10^{-43}$ GeV.
