Noncommutative Gravity and the Standard-Model Extension
Charles D. Lane
Noncommutative geometry has become popular mathematics for describing speculative physics beyond the Standard Model. Noncommutative QED has long been known to fit within the framew…
Relating Noncommutative SO(2,3) Gravity to the Lorentz-Violating Standard-Model Extension
Quentin G. Bailey, Charles D. Lane
We consider a model of noncommutative gravity that is based on a spacetime with broken local SO(2,3) symmetry. We show that the torsion-free version of this model is contained with…
Spacetime Variation of Lorentz-Violation Coefficients at Nonrelativistic Scale
Charles D. Lane
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 conseq…
Spacetime Variation of Lorentz-Violation Coefficients at Nonrelativistic Scale
Charles D. Lane
The notion of uniform and/or constant tensor fields of rank is incompatible with general curved spacetimes. This work considers the consequences of certain tensor-valued coeff…
Probing Lorentz violation with Doppler-shift experiments
Charles D. Lane
We analyze Doppler-effect experiments in terms of a general framework for violations of Lorentz symmetry: the Standard-Model Extension. These experiments are found to be sensitive…
Probing Lorentz and CPT violation with space-based experiments
Robert Bluhm, Alan Kostelecky, Charles Lane +1
Space-based experiments offer sensitivity to numerous unmeasured effects involving Lorentz and CPT violation. We provide a classification of clock sensitivities and present explici…
