The study focuses on asymmetric and hybrid steering in the Tavis-Cummings model with dipole-dipole interaction (DDI) under intrinsic decoherence, using entropic uncertainty inequalities between two identical atoms for evaluation. The results indicate that phase decoherence stabilizes the direction during time decay. The DDI coupling in the system enhances bi-directionality and stability, while avoiding collapses and violations that affect asymmetric and hybrid steering, respectively. When intrinsic decoherence is introduced, the asymmetric direction remains stationary for weak DDI coupling, while the hybrid direction tends to have the same characteristics for strong DDI coupling.
Asymmetric and hybrid steering, evaluated by entropic uncertainty inequalities between two identical atoms, is studied in the Tavis-Cummings model with dipole-dipole interaction (DDI) under intrinsic decoherence. The results show that phase decoherence stabilizes the direction during time decay. DDI coupling in the system enhances bi-directionality and stability by avoiding collapses and violations, from which the asymmetric and hybrid steering suffer, respectively. When intrinsic decoherence is introduced, the asymmetric direction becomes stationary when DDI coupling is weak. However, the hybrid direction tends to have the same characteristics when DDI coupling is strong.
