标题： Quantum Geometry and Thermal Radiation from Black Holes

摘要： 最近在非微扰量子引力框架下提出的黑洞态的量子力学描述被用于研究量子黑洞的发射和吸收光谱。 我们假设量子黑洞的态的概率分布由“面积”正则系综给出，在其中用视界面积代替能量，并利用费米黄金法则来求解谱线强度。 对于一个不旋转的黑洞，我们研究了s波的吸收和发射，考虑了一组特殊的发射线。 为了找到谱线强度，我们将黑洞的一个微观态与原子气体的一个态进行了类比。 显示英文摘要

摘要： A quantum mechanical description of black hole states proposed recently within non-perturbative quantum gravity is used to study the emission and absorption spectra of quantum black holes. We assume that the probability distribution of states of the quantum black hole is given by the ``area'' canonical ensemble, in which the horizon area is used instead of energy, and use Fermi's golden rule to find the line intensities. For a non-rotating black hole, we study the absorption and emission of s-waves considering a special set of emission lines. To find the line intensities we use an analogy between a microscopic state of the black hole and a state of the gas of atoms.
