    "abstract": "In this work, we report that the Hawking radiation effect on fermions is\nfundamentally different from the case of scalar particles. Intrinsic properties\nof fermions (exclusion principle and spin) affect strongly the interaction of\nfermions with both Hawking radiation and metric of the spacetime. In particular\nwe have found the following: first, while the fermion vacuum state seen by the\nRindler observer is an entangled state in which the right and left Rindler\nwedge states appear in correlated pairs as in the case of the scalar particles,\nthe entanglement disappears in the excited state due to the exclusion\nprinciple; second, the spin of the fermion experiences the Winger rotation\nunder a uniform acceleration; and third, the quantum information of fermions\nencoded in spin (entangled state is composed of different spin states but with\nthe same mode function) is dissipated not by the Hawking radiation but by the\nWigner rotation as the pair approaches the event horizon.",
