# Black Hole as a Quantum Field Configuration

@article{Kawai2020BlackHA, title={Black Hole as a Quantum Field Configuration}, author={Hikaru Kawai and Yuki Yokokura}, journal={arXiv: High Energy Physics - Theory}, year={2020} }

We describe 4D evaporating black holes as quantum field configurations by solving the semi-classical Einstein equation $G_{\mu\nu}=8\pi G \langle \psi|T_{\mu\nu}|\psi \rangle$ and quantum matter fields in a self-consistent manner. As the matter fields we consider $N$ massless free scalar fields ($N$ is large). We find a spherically symmetric self-consistent solution of the metric $g_{\mu\nu}$ and state $|\psi\rangle$. Here, $g_{\mu\nu}$ is locally $AdS_2\times S^2$ geometry, and $|\psi\rangle… CONTINUE READING
