Title：Black Hole Information Paradox and Double Holography
Over the past decade, concepts and techniques from quantum information theory have provided valuable insights into quantum field theory, condensed matter physics, and quantum gravity. Recent advances have allowed a better understanding of the black hole information paradox. A formula known as the "island formula" was discovered to calculate the fine-grained entropy of Hawking radiation. In this talk, I will give a brief overview of recent progress on the information paradox over the last few years. In particular, I will focus on models based on so-called double holography. We also use double holography to study a system of two entangled gravitating universes. With the thermalization of the bath region, the holographic universe presents the process of gravitational collapse and eventually forms a black hole.
