Multi-spin particle tunneling and black hole thermodynamics: GUP-corrected zitterbewegung and exponentially modified entropy

We investigate how the combined influence of spin-gravity coupling and the Generalized Uncertainty Principle (GUP) modifies the evaporation dynamics of a ( 3 + 1 ) -dimensional Reissner-Nordström (RN) black hole. Using Barut’s covariant zitterbewegung formalism, we derive a spin-dependent, GUP-deformed Hamilton-Jacobi equation governing the tunneling of particles with intrinsic spins s = 1 / 2 , 1 , 3 / 2 , 2 . The resulting corrections to the Hawking temperature reveal that the interplay between spin-curvature coupling and GUP effects introduces distinct thermodynamic behaviors across spin sectors: low-spin particles exhibit enhanced tunneling and dominate early-stage radiation, while higher-spin modes…
