论文摘要
我们研究了$ d = 4 $双场理论中球形溶液的鹰辐射的基本特性。我们给出溶液的鹰温度的表达，然后讨论各种限制的结果。我们发现，对于所有这些限制，只有Schwarzschild解决方案，而F-JNW解决方案可以产生鹰辐射。此外，我们在$ d = 4 $ double场理论中获得了灰体因子的下限$σ_l（ω）$。特别是，我们计算F-JNW解决方案的灰色因子$σ_l（ω）$的绑定。对于F-JNW解决方案，$σ_l（ω）$单调增加，固定$ b（a）$的$ a（b）$的增加。
We investigate the basic properties of Hawking radiation for spherical solutions in $D = 4$ double field theory. We give the expression of the Hawking temperature for the solution and then discuss the results of various limits. We find that for all these limits only Schwarzschild solution and F-JNW solution can generate Hawking radiation. Moreover, we obtain the lower bound on greybody factors $σ_l(ω)$ for the spherical solutions in $D = 4$ double field theory. In particular, we calculate the bound on greybody factors $σ_l(ω)$ for F-JNW solution. For F-JNW solution, $σ_l(ω)$ monotonically increases with the increase of $a(b)$ for fixed $b(a)$.
