论文摘要
非平凡$ 4 $二维的爱因斯坦 - 加斯 - 波尼特重力理论的骨气场的准模式在[D.〜Glavan and C.〜lin，phys。在这里，我们计算了这款新颖的$ 4D $ EINSTEIN-GAUSS-BONNET理论的球形渐近黑洞的狄拉克场的准模式。通过6阶WKB方法计算出具有PADé近似值的第6阶WKB方法和时间域的积分的准频率值表明，当耦合常数增长时，准模式的实际部分大大增加，而阻尼速率通常会降低。
While quasinormal modes of bosonic fields for the non-trivial $4$-dimensional Einstein-Gauss-Bonnet theory of gravity suggested in [D.~Glavan and C.~Lin, Phys.\ Rev.\ Lett.\ {\bf 124}, 081301 (2020)] have been recently studied, there is no such study for fermionic fields. Here we calculate quasinormal modes of the Dirac field for spherically symmetric asymptotically flat black hole in this novel $4D$ Einstein-Gauss-Bonnet theory. The values of the quasinormal frequencies, calculated by the 6th order WKB method with Padé approximants and the time-domain integration, show that the real part of the quasinormal modes is considerably increased, while the damping rate is usually decreasing when the coupling constant is growing.
