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…
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…
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…
Atomic Probes of Noncommutative Field Theory
Charles D. Lane
We consider the role of Lorentz symmetry in noncommutative field theory. We find that a Lorentz-violating standard-model extension involving ordinary fields is general enough to in…
Clock-Comparison Tests of Lorentz and CPT Symmetry in Space
Robert Bluhm, Alan Kostelecky, Charles Lane +1
Clock-comparison experiments conducted in space can provide access to many unmeasured coefficients for Lorentz and CPT violation. The orbital configuration of a satellite platform…
