Schwarzschild-dS黑洞中的大质量Dirac拟正规模:反常衰变率和精细结构

Massive Dirac quasinormal modes in Schwarzschild-dS black holes: anomalous decay rate and fine structure

Almendra Aragón, Ramón Bécar, P. A. González, Yerko Vásquez

摘要:

最近,人们研究了在标量场扰动下某些几何结构的准正规模的反常衰减率,这种反常衰减率发生在最长寿命模是具有较高角数的模,以及存在一个临界标量场质量,即标量场质量的值使得衰减率不明显依赖于角数,并且超过该值,衰减速率的行为被反转。在这里,我们考虑在Schwarzschild de Sitter黑洞的背景下的费米场的传播,我们表明,反常的衰变率行为和精细结构,相关的手征和质量之间的耦合场,可以观察到的费米光谱。

英文摘要:

Recently, the anomalous decay rate of quasinormal modes has been studied for some geometries under scalar field perturbations, which occurs when the longest-lived modes are the ones with higher angular number, as well as, the existence of a critical scalar field mass, i.e the value of scalar field mass such that the decay rate does not depend appreciably on the angular number, and beyond which the behaviour of the decay rate is inverted. Here, we consider the propagation of fermionic fields in the background of Schwarzschild de Sitter black holes, and we show that the anomalous decay rate behaviour and the fine structure, related to the coupling between the chirality and the mass of the field, can be observed in the fermionic spectrum.
