Spin effects on particle creation and evaporation in f(R, T) gravity

Abstract In this work, we study how the spin of particle modes influences particle creation, greybody factors, absorption, and evaporation of a black hole within the framework of modified electrodynamics in f ( R , T ) gravity, recently proposed in Róis et al. (Phys Rev D 111(12):124044, 2025). All spin sectors-scalar, vector, tensor, and spinorial-are analyzed to obtain the corresponding features. For particle creation, we consider massless bosonic and fermionic perturbations to determine the r
