# Lorentz and CPT tests with spin-polarized solids

@article{Bluhm2000LorentzAC, title={Lorentz and CPT tests with spin-polarized solids}, author={Bluhm and Kosteleck{\'y}}, journal={Physical review letters}, year={2000}, volume={84 7}, pages={ 1381-4 } }

Experiments using macroscopic samples of spin-polarized matter offer exceptional sensitivity to Lorentz and CPT violation in the electron sector. Data from existing experiments with a spin-polarized torsion pendulum provide sensitivity in this sector rivaling that of all other existing experiments and could reveal spontaneous violation of Lorentz symmetry at the Planck scale.
