Dynamical noncommutativity

The model of dynamical noncommutativity is proposed. The system consists of two interrelated parts. The first of them describes the physical degrees of freedom with the coordinates q1 and q2, and the second corresponds to the noncommutativity Delta *h which has a proper dynamics. After quantization, the commutator of two physical coordinates is proportional to the function of Delta *h. The interesting feature of our model is the dependence of nonlocality on the energy of the system. The more the energy, the more the nonlocality. The leading contribution is due to the mode of noncommutativity; however, the physical degrees of freedom also contribute in nonlocality in higher orders in Delta *c.
