霍金辐射和维格纳旋转对费米子纠缠的影响

Effects of Hawking radiation and Wigner rotation on fermion entanglement

Doyeol Ahn

摘要:

在这项工作中,我们报告说,霍金辐射对费米子的影响是根本不同的情况下的标量粒子。费米子的内禀性质(不相容原理和自旋)强烈地影响了费米子与霍金辐射和时空度规的相互作用。特别是我们发现:第一,当Rindler观察者看到的费米子真空态是一个纠缠态时,其中左右Rindler楔态与标量粒子一样出现在关联对中,但由于不相容原理,纠缠在激发态中消失;第三,自旋编码的费米子(纠缠态是由不同的自旋态组成,但具有相同的模函数)的量子信息在接近事件视界时不是被霍金辐射耗散,而是被维格纳旋转耗散.

英文摘要:

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