标题： Influence of gravity on the quantum speed limit in neutrino oscillations

摘要： 量子速度极限（QSLs）决定了量子系统从初始状态演化到最终状态所需的最短时间。 我们研究了在引力场存在的情况下，中微子-反中微子系统的幺正演化中的 QSLs。 已知在一重味和二重味框架下，中微子与反中微子之间的跃迁概率取决于引力场的强度。 二重味系统中的 QSL 时间行为表明，随着引力场强度的增加，味转换变得更快。 随后，我们在接近旋转的原初黑洞时，通过探索二重味振荡纠缠熵的速度极限，观察到纠缠迅速被抑制。 显示英文摘要

摘要： The quantum speed limits (QSLs) determine the minimal amount of time required for a quantum system to evolve from an initial to a final state. We investigate QSLs for the unitary evolution of the neutrino-antineutrino system in the presence of a gravitational field. It is known that the transition probabilities between neutrino and antineutrino in the framework of one and two flavors depend on the strength of the gravitational field. The behavior of the QSL time in the two-flavor system indicates fast flavor transitions as the gravitational field strength increases. Subsequently, we observe quick suppression of entanglement by exploring the speed limit for entanglement entropy of two-flavor oscillations in the neutrino-antineutrino system in the proximity of a spinning primordial black hole.
