Abstract

Geometry is quantized in loop quantum gravity. As a step toward building a detailed phenomenology of this discrete geometry a model of an atom of geometry is reviewed. The model, which preserves local Lorentz invariance, exhibits a lever arm that raises the scale at which the granularity in angle becomes apparent. The signature of this effect is a systematic shift of observed angles in processes such as high energy particle scattering experiments. To check assumptions in the model, coherent states of a simple atom of spatial geometry are explored using information intrinsic to the quantum state.
