Noncommutative geometry of the quantum clock

Publication date: Available online 16 January 2019Source: Physics Letters AAuthor(s): S. Mignemi, N. UrasAbstractWe introduce a model of noncommutative geometry that gives rise to the uncertainty relations recently derived from the discussion of a quantum clock. We investigate the dynamics of a free particle in this model from the point of view of doubly special relativity and discuss the geodesic motion in a Schwarzschild background.
