Generalized Uncertainty Principle as a Mechanism for CP Violation

Within quantum electrodynamics we show that the Generalized Uncertainty Principle induces higher-derivative corrections that promote the topological invariant $F_{\mu\nu}\,\widetilde F^{\mu\nu}$ to the dynamical, non-topological operator $\partial^\lambda F_{\mu\nu}\,\partial_\lambda \widetilde F^{\mu\nu}$. We explore the resulting phenomenology, focusing on the generation of electric dipole moments. Our findings open a new low-energy window for testing quantum-gravity scenarios through precision measurements of charge-parity violation.
