Holography with End-of-the-World Branes and Quantum Entanglement
Abstract: Holography relates quantum many-body systems to gravitational theories. Quantum entanglement plays a key role to explain how the spacetime geometries in gravity emerge from quantum systems. A new class of holography can be found by introducing so called end-of-the-world branes and has been actively studied recently. Such holographic models describe quantum systems with boundaries, such as boundary conformal field theories (BCFTs), where the boundary dynamics is described by gravitational degrees of freedom localized on the branes. Considerations of quantum entanglement in these setups help us to have deep insights on the black hole information problem. At the same time, they can also be used to analyze quantum information aspects of non-equilibrium processes. In this talk, I will explain these developments.
