SUMMARY:Quantum Black Hole from Quantum Matter\, Dr. Yuki YOKOKURA (KEK\, J
 apan)
DESCRIPTION:Quantum effects of matter are indispensable for revealing the\n
 true nature of black holes\, such as the time evolution of quantum states\
 nduring collapse and evaporation\, the origin of the entropy-area law\, an
 d\nthe back-reaction of quantum fluctuations of matter fields on spacetime
 \nwith high curvatures. We employ two methods and construct a\nnon-perturb
 ative self-consistent solution to the semi-classical Einstein\nequations. 
 This yields a compact\, high-density configuration without a\nhorizon. A q
 uantum pressure consistent with the 4D Weyl anomaly arises\ninside\, elimi
 nating classical singularities. Incorporating self-gravity\neffects and in
 tegrating the entropy density of the matter field over\nvolume exactly rep
 roduces the entropy-area law. The imaging (shadow) is\nconsistent with tha
 t of the classical case (with a tidy deviation).\nFurthermore\, we conside
 r an effective dynamics beyond the semi-classical\napproximation\, describ
 ing the interior fully up to the origin. This talk\nwill outline these res
 ults. [arXiv:2002.10331\, 2207.14274\, 2309.00602\,\n2403.09388\, 2507.183
