• Abstract summary: In the infinite Hawking temperature limit, the physically accessible correlations does not vanish only in the fermionic case. The higher frequency modes can sustain correlations for the finite Hawking temperature. Since the MIN for the latter modes quickly diminishes, the increased frequency may be a way to maintain nonlocal correlations for the scenarios at the finite Hawking temperature.

• Abstract: We present a systematic and complementary study of quantum correlations near a black hole by considering the measurement-induced nonlocality (MIN) in the noninertial frames. The quantum measure of interest is discussed on the same footing for the fermionic, bosonic and mixed fermion-boson modes in relation to the Hawking radiation. The obtained results show that in the infinite Hawking temperature limit, the physically accessible correlations does not vanish only in the fermionic case. However, the higher frequency modes can sustain correlations for the finite Hawking temperature, with mixed system being more sensitive towards increase of the fermionic frequencies than the bosonic ones. Since the MIN for the latter modes quickly diminishes, the increased frequency may be a way to maintain nonlocal correlations for the scenarios at the finite Hawking temperature.

  We examine the evolution of quantum entanglement and a few quantum correlations beyond entanglement, local quantum uncertainty and measurement-induced nonlocality. The steady state quantum correlations, being independent of the initial state, are found to remain all non-zero for low, finite temperatures.

  Recently, it was suggested that the Hawking radiation may originate not at the event horizon but in the quantum region outside of it, known as the quantum atmosphere. The present study attempts to explore this argument further by assessing its role in shaping quantum correlations near a black hole.
