Abstract

The gravitational radiation in dynamical non-commutative spaces (DNCS) is explored. we derive the corrections due to dynamical noncommutativity on the gravitational potential. We obtain the DNC corrections on the angular velocity as well as the radiated power of the system. By calculating the period decay of the system and using the observational data we obtain an upper bound for the DNS parameter {\tau} . We also study quantum interference induced by gravitational potential in usual non-commutative and dynamical non-commutative spaces. The phase difference induced by gravity is calculated on two different paths and then, it is compared with the phase difference induced by gravity in commutative space.
