摘要

我们研究了由环量子引力（LQG）驱动的有效量子修正的非奇异黑洞模型的热力学。有效几何结构具有一个过渡面，连接具有相同质量的捕获区和反捕获区。有一个最小质量，视界温度和科玛能量为零，黑洞停止霍金蒸发。对于超过这个极限的视界，我们给出了灰体因子、发射光谱和质量损失率，并求解了一个一维Schrödinger-type方程，该方程具有有效的短程势垒，适用于自旋0、1和2的无质量场。

Thermodynamics of effective loop quantum black holes

We study the thermodynamics of a non-singular black hole model with effective quantum corrections motivated by Loop Quantum Gravity (LQG). The effective geometry has a transition surface that connects trapped and anti-trapped regions with the same mass. There is a minimum mass for which the horizon temperature and Komar energy are zero, and the black hole stops its Hawking evaporation. For horizons above this limit, we present the grey-body factors, emission spectra, and the mass loss rate, solving a one-dimensional Schrödinger-type equation with an effective short-range potential barrier for massless fields of spins 0, , 1 and 2.
