We analyze the effects of uniformly rotating frame on an interacting electron (𝑒− ) antielectron

(𝑒+) pair in a topological defect-induced three-dimensional geometric background. Considering

that these particles interact via a Coulomb-type interparticle interaction potential, we solve the

corresponding fully-covariant two-body Dirac equation in the rotating frame of cosmic stringgenerated

spacetime background. As a result, we obtain an energy spectrum in closed form and

discuss the effects of uniformly rotating frame on the energy of such a 𝑒− 𝑒+pair. We apply this

energy spectrum for Positronium system and analyze the effects of the uniformly rotating frame

and spacetime topology effects on the energy of spin symmetric and spin antisymmetric quantum

states of the system in question. We obtain that the angular velocity of the uniformly rotating frame

decreases the magnitude of binding energy of the considered composite structure. In addition, we

show that the angular velocity of the uniformly rotating frame increases the decaytime of the

damping modes for spin antisymmetric quantum state of the system in question. Our results show

that it can be possible to actively tune the binding energy and decaytime of such systems, in

principle.
