U.S.-Mexico Cooperative Research: Canonical Quantum Gravity and Gravitational Collapse

9800867 Kuchar美国-墨西哥奖将支持犹他大学的Karel Kuchar教授与墨西哥国立自治大学（UNAM）原子核科学研究所的Jemal Guven教授和Michael Ryan教授之间的合作研究。研究人员打算研究经典量子引力能揭示什么关于引力坍缩的信息。目标是超越半经典近似，并获得一些关于量子几何在广义相对论和量子理论预测的最令人困惑的过程之一中所引起的影响的见解：黑洞的形成是由引力坍缩和霍金辐射的蒸发。库查尔教授在犹他大学的研究涉及天体物理学/计算工作以及与相对论和量子化的数学基础有关的研究。墨西哥小组规模庞大，涉及多个学科，涵盖量子引力、相对论天体物理学、经典宇宙学、变分原理、黑洞物理学以及物理学各个分支的几何方法。研究人员的互补专业知识构成了预期合作的基础。＊＊＊

9800867 Kuchar This U.S.-Mexico award will support collaborative research between Prof. Karel Kuchar of the University of Utah and Prof. Jemal Guven and Prof. Michael Ryan of the Instituto de Ciencias Nucleares of the Universidad Nacional Autonoma de Mexico (UNAM). The researchers intend to examine what canonical quantum gravity can reveal about gravitational collapse. The goal is to go beyond semiclassical approximations and gain some insights about the effects induced by quantum geometry in one of the most puzzling processes predicted by general relativity and quantum theory: the formation of a black hole by gravitational collapse and its evaporation by Hawking radiation. Prof. Kuchar's research at the University of Utah involves both astrophysical/computational work and research related to the mathematical foundations of relativity and quantization. The Mexican group is large and multidisciplinary, covering quantum gravity, relativistic astrophysics, classical cosmology, variational principles, black hole physics, and geometric approaches to various branches of physics. The complementary expertise of the researchers forms the basis for the intended collaboration. ***
