Description
Quantum effects of matter are indispensable for revealing the true nature of black holes; the time evolution of quantum states during collapse and evaporation, the origin of the entropy-area law, and the back-reaction of quantum fluctuations of matter fields on spacetime with high curvatures. In various approaches, we obtain a non-perturbative self-consistent solution to the semi-classical Einstein equation. It represents a compact dense configuration without a horizon. A quantum pressure consistent with 4D Weyl anomaly arises inside, eliminating classical singularities. Integrating the entropy density of the matter fields over volume exactly reproduces the entropy-area law due to self-gravity. The imaging is consistent with that of the classical black hole. Furthermore, an effective dynamics beyond the semi-classical approximation describes the interior fully up to r=0. This talk will outline these results.
