Microcausality without Lorentz invariance
Abstract Microcausality — the vanishing of commutators outside the lightcone — is a fundamental property of relativistic quantum field theories. We derive its implications for two-point functions of scalar operators on Lorentz-breaking states. We restrict to spatially homogeneous and isotropic state...
